Make Copper Chloride (3 ways)

[@origamigek]

I love how the most asked question on chemistry video's is about the stir bar.

[@69iron69]

One more method is to mix a solution of: CuSO4(aq) + CaCl2(aq) --> CuCl2(aq) + CaSO4(s) With calcium sulfate being so insoluble the sulfate contamination would be greatly reduced also no acids are used. Glad you're making videos again!

[@gianfrancomussi6063]

CuCl2 +C2H2 -> C2Cl2 +HCl😫

[@Anticlimacticgrocerybag]

Hey man how's your life going?

[@Lawbase]

I'm glad you're back nurdrage. :)

[@NurdRage]

I promise to have the crowd funding thing ready by next video. Even if it kills me.

[@brainandforce]

I wonder if tetrachlorocupric acid can be isolated.

[@NurdRage]

Brain&Force ya know what, it can be. You dissolve copper chloride in very highly concentrated hydrochloric acid (40%) and evaporate it (or chill it) and let it crystalize. The crystals are H2CuCl4, and they're brilliant green. Very pretty actually. I'm not sure how pure it is though.

[@shadowphyre4746]

NurdRage How concentrated should be the HCl?

[@NurdRage]

Shadowphyre in my video i used 30%, you can use any concentration down to 10%. Below that the reactions will still work but can be exceedingly slow or very low yielding.

[@shadowphyre4746]

NurdRage Ok thanks you.

[@DameAndThatGame]

iv used this technique before, with memory boards, its took the copper plating off from under the gold and was able to retrieve the gold fro refining, was a fun process :)

[@adelinyoungmark1929]

you can also start with copper oxide which will greatly speed up the process. basically just make a bunch of copper powder/sponge via electrolysys and then heat it up with an oxidising flame (i.e a propane torch) this makes a very fine copper oxide powder which has a very high surface area and reacts almost imeadiatly.

[@angst_]

I (tried to) dissolve 2mol copper wire(127g) in 400ml of HCL (10molar). I've been bubbling it for 3 weeks! It's super dark brown and hasn't dissolved half the copper yet. What should I do? I was patient to learn chemistry before beginning and even did my own stoichiometry research (I came to the same balanced reaction as you have at 00:34). Here's a kind of interesting observation I made during the process: After bubbling the solution for a few days or so the HCL remained clear. Giving the bottle a shake would turn the HCL DARK brown, almost black. Letting it sit for 15-30 minutes it slowly cleared up back to crystal clear! So odd.

[@TrevourAJones]

Making Copper(II) Acetate solution and mixing in Sodium Chloride also does the trick. Although you also end up with Sodium Acetate, but if you let the solution dry out to form Copper(II) Chloride and Sodium Acetate, you can remove most of the Sodium Acetate and any left over Sodium or Acetate ions through rinsing with distilled water and filter out the Copper(II) Chloride. You will lose a tiny bit of the Copper(II) Chloride, since it is slightly soluble in water, but its a miniscule amount.

[@bonbonpony]

It would be cool to see this production method too, since I don't have hydrochloric acid and I don't know where could I get one. I have plenty of table salt and vinegar though. Maybe you know of some video that shows this process?

[@user-pr6ed3ri2k]

@@bonbonpony copper doesn't really react with any acid unless it's oxidized

[@bonbonpony]

@@user-pr6ed3ri2k I know now. That's why I added some hydrogen peroxide to start the reaction back then, and it worked with vinegar just fine ;)

[@garethdean6382]

I've found copper sulphate mixed with calcium chloride (Damp Rid) and filtered works both quickly and gives a pure product. And you avoid acids which is always nice.

[@satina1169]

Very smart solution, noted this one

[@mm-jq2bo]

How much water did you use?

[@mm-jq2bo]

I added 2g of CuSO4.5H2O and 0.889g of CaCl2 in a beaker, and then I added Milli-Q water. I dont know how much water I need to add and the result product has a white power too. I am not sure I did it right or not. Anyone knows, please help me...

[@RandomExperiments]

I prefer to mix copper sulfate solution with excess sodium hydroxide in hot solution to get black copper oxide, which can be filtered off, washed and dissolved in HCl, to get a clean product.

[@boltblast3262]

Couldn't you get rid of any sulfate ions by reacting the copper sulfate solution with calcium chloride rather than HCl by causing all of the sulfate ions to combine with the calcium ions and precipitate as calcium chloride. CuSO4 + CaCl2 = CuCl2 + CaSO4 (aq) (aq) (aq) (s)

[@endothermicexothermic4051]

Pb and Ba too, for economics problem.....Pb is suggested

[@jonasstrzyz2469]

Instead of dissolving Copper(II)sulphate in hydrochloric acid. Why do you not simply make basic copper carbonate, and let the basic copper carbonate react with hydrochloric acid? Sound cleaner to me.

[@balintelias]

I made basic copper carbonate from CuSO4 and baking soda, then dissolved it in HCl. The result doesn't look quite pure in its crystal form, but it gives a clear green solution when dissolved in water.

[@rubengonzalez2233]

You should show how to make homemade polyvinyl alcohol plz and Thx u , greatly appreciated

[@Kotesu]

Something I've always wondered was could you stabilize Copper (I) Chloride with a complex of some sort and use it for plating copper in a manner similar to Tollen's reagent? If that were possible you'd have a great method to make low cost PCB's on cheap substrates like microscope slides.

[@alexstone691]

That sounds really interesting

[@JustinHallPlus]

This video totally answered my question from the last video!

[@moogyboy6]

I would assume that since you don't specify a quantity of copper to start with, we just use an excess, ie a lot, and just dump the unreacted copper. Also, does the concentration of hcl matter?

[@aaronmckain4661]

Man I love you videos, something about your voice brings happiness and some discomfort.....idk

[@materioverda1655]

Hi, is it possible that what you have produced during aeration is tribasic copper chloride? BTW, can you make a video on producing tribasic copper chloride? Thanks

[@snakedragon205]

can you reuse the copper Chloride when it is used

[@jeremisobierski8424]

I made copper (II) chloride with the second method, using 3% peroxide, and at first, everything was fine, but after a 3 hours, I noticed that the bottom turned dark brown. If someone knows why did it turned brown, then please tell me how to fix it, or what did I do wrong (maybe that's because I mixed the acid and the peroxide first, then added the copper.

[@WrenagadeWorkshop]

Hi Nerdrage :) Your videos have been a fantastic source of entertainment and learning. They have helped me a lot and for that I thank you good sir. You mention that copper chloride gets stronger as it's used but didn't catch anything about diluting it. If poss, I'd like to find a suitable strength/etch time that I can monitor and have some spent CuCi2 kicking around which I need to do something about. I then started wondering if it could be used for diluting the solution but wasn't sure. If not, is it just a case of adding fresh hydrochloric and water?

[@tommyzhao6600]

Can you just boil down the solution to get solid copper chloride?

[@boldizsarbalog6206]

It's working too, if you put some salt (NaCl) and some copper-suplhate (CuSO4) with a bit water together and warm it, it works very well. :) (Put some alufoil into it, and ignite the gas!)

[@Psychaotix2001]

Just a quick question. Would the reaction in the first method (Bubbling air through the solution) speed up if I used, say, an O2 bottle from an oxyacetylene kit with the regulator JUST cracked open to create a slow stream of bubbles? I suspect it would, but confirmation would be nice too.

[@einarhk]

What did you drop into the glass to make the stirring?

[@TheIdeanator]

Gold recovery? If you can I'd enjoy seeing a video on that.

[@piranha031091]

How about reacting copper sulphate with sodium hydroxide to get a copper hydroxide precipitate, filtering it out and rinsing it with water to remove remaining sodium sulphate and excess hydroxide, and then redissolving it in hydrochloric acid?

[@NurdRage]

piranha031091 absolutely! you can also use sodium carbonate and sodium bicarbonate. There are dozens and dozens of ways to make copper chloride. :)

[@venator886]

NurdRage Lets say I add NaNH4.Would that result in copper forming Cu[NH3]4 and staying in solution while the SO4 would percipitate as Na2SO4 which I could then filter and afterwards add more HCL to turn the copper complex back into CuCl2?

[@TheHotmud]

piranha031091 I've found copper hydroxide to be somewhat difficult to filter, it was always a gooey kind of mass whenever I made it.

[@WrenagadeWorkshop]

Excellent video, just made up a batch and it worked a treat :) Can it be used as is indefinitely, or will I need to eventually dilute the mix due to excess copper? If so, is it just a case of adding more 36% hydrochloric?

[@rohankunder1006]

How will u determine the exact percentage of copper in cuprous chloride...... By instrumental analysis

[@itsjustpyro9784]

Can someone help me out with a reaction as Im really at a loss. So I made CuCl2 by this method and ended up with the dark green solution which was very acidic. I then wanted to make copper carbonate. so to this solution i added solid sodium carbonate which took many additions each releasing CO2 (which took more from excess HCl) When the final addition of sodium carbonate was added, the solution precipitated a brilliant orange precipitate and not blue copper carbonate! The orange precipitate is insoluble and doesn't change colour upon diluting with water. Im sure there were no contaminants in the process and i will repeat it to be sure. Am i missing a simple fundamental of chemistry or have I discovered something? :D Thank you to anyone who takes the times to read this, even if you're just as lost as me.

[@davideormenese5523]

Maybe you've used copper coins and your solution was made of copper II chloride and iron II chloride (because euro cents and other coins are made of copper plated steel) and when you added sodium carbonate iron III carbonate precipitated

[@OdinsWolves_Video]

Any suggestions? I have a dirty solution of copper, gold and gold jerlery alloyed metals, most likely silver and zinc mostly, I added hcl by mistake, (no lable)🤔 when I was dissolving base metals, I need to extract any gold that may have dissolved but all that perciputated looks like a mix of smb and copper cloride?

it does. it also let's off chlorine gas so try not to breathe that stuff in.

[@ericami5642]

Would using 30% peroxide make this go faster

[@bronsonstephens5799]

Wait but. What would happen if I just took distilled water. Mixed sodium chloride or baking soda in and then put in two electrodes (with the positive one being copper)? I did this. And it made my solution blue. So do I have some kind of copper solution? Also. I was able to coat a nickel with a very thin layer of copper.

[@spiros1994]

What is this thing that is placed inside the "bottle" and rotating?

[@seigeengine]

spiroslouis1 A stir bar. It's a (usually) teflon coated magnet that gets spun by a spinning magnet in the stir plate he put it on.

[@DreamsOfMorpheus]

seigeengine are there some solutions that can't be stirred with that?

[@seigeengine]

***** Yes, but it's generally a good bet. It's a lot like the glass they make chemistry equipment out of. Yes, there are things it will react with, but it won't react with almost everything, and that's close enough. Assuming I haven't herped my teflon coated derps, teflon's carbon fluorine bonds are extremely strong, meaning hard to break, meaning it's unlikely teflon will react with whatever you put it in. But as with all chemistry, know about your chemicals before using them. In chemistry it's git gud or git ded. Or horribly maimed anyway.

[@Yukicanis]

How about using copper oxide instead of copper sulfate? Wouldn't that directly produce copper chloride whith just water as a byproduct?

[@dylandesrosiers9305]

In the second method, will all the copper disappear by the end of the couple of hours it is stirring?

[@delciotto]

would this be cheaper or more expensive than just buying the copper chloride (not taking in account the price of equipment to make the copper chloride)

[@Lorenzo_Mella]

NurdRage Some months ago I made a solution on something that may was FeCl3: I made a solution of table salt, until saturation was reached. Then I took two iron electrodes connected to a USB cable and ran the current, making sure that the electrodes were touching the crystals of salt. Then a nasty, brownish-yellow subtance was produced. Can it be a cheap way to produce FeCl3 without using complex materials or expensive lab devices?

[@NourSelim0]

Heavy97Metal I don't think Iron can substitute Sodium or Potassium in a solution (table salt is a mixture of NaCl and KCl), substitution would happen the other way round though, because Sodium and Potassium form stronger ionic bonds than Iron.

[@Lorenzo_Mella]

Hi Hassan, I'm not that good at chemistry, and I'm quite guessing, but could have happened something like this: The electricity with the NaCl produced Cl_2 (and other compounds), which could react with the iron electrodes to form FeCl3? I onestly don't know, I just thought that the clorine smell and the brownish solution could only be produced by the ferric chlorine (sorry for my bad english ;) )

Hi ! im pretty new in the chemistry world and this is one of the first things i wanted to make. My supplies suck but i tried my best. I tried to follow your video, now calculations all by eye xd. Half muriatic acid half hydrogen peroxyde and a chips of copper (from 0,5mm wire). It went pretty fine turning green and stuff. Later that day was Dark Green so i decided the next step would be to evaporate the water (it might have been acid so shi* :p). What happened was something really weird but these are the variables: The recipient was a dirty pot and the temperature was unknown, as it boiled the sides looked a greenish blue and i thought that was good but as it finished boiling it looked really weird. it was bumpy, shiny, and the colour was like a dark green rgb(102, 102, 51) more or less. my teacher described it as an amalgam or i dont know how its spelled XD. i put some water in a sample and dissolver really well. WEIRDER in the bottom was a white salt that dint dissolve. Next day the sample with the salt that dint dissolve, the water turned kinda yellow. The Pot that i boilled turned dark (i suppose copper oxide?) and some bubbles that were there popped and revealed a solid that looked like copper chloride! (im not sure yet). When i tried mixing it with water, there was some solids in suspension that dint mix (i think it is copper oxide) and the water was brown. AFTER ALL THIS!!!! does anyone know anything that can help me! XD thx ;)

[@neutronpcxt372]

I can help. The only thing you need is actually HCL, a power supply, alligator clips, and some copper wire. You basically want to make electrolysis of copper to get copper chloride in the solution.

[@AndAbel-AOD]

[@jamesomalley5208]

yes I have one question I watched a video on recycling gold and they used copper chloride solution but the solution he was using was a very nice green color compared to the solutions that you make which almost look dark brown what is the difference between the two the lighter one and the darker one love your videos and thank you very much

[@NurdRage]

+James O'Malley mine are *extremely* concentrated. So the colors are darker. Also, mine tend to also have copper(I) ions mixed in with the more plentiful copper(II) ions. The mixture of ions creates what are called "charged transfer complexes" that are very dark and have a dirty green color rather than a clean bright color. If i added more water to my solutions and bubbled in more air or added more hydrogen peroxide, they would also become bright green.

[@Giblet12]

Could you use this to extract the copper coating from pennies? I was thinking of using the copper coating on pennies to form copper chloride, and then precipitate the copper using aluminum wire.

[@angst_]

No. HCL reacts with Zinc to make Hydrogen gas and Zinc Chloride. The result will be the opposite and leave you with a hollow penny. HCL doesn't react with pure copper, only copper oxide. So, it would slowly eat a hole through the copper coating as the copper slowly corroded from the oxygen and water. Once it reached the zinc center it would hollow it out. I only know this because it's a popular science class experiment.

[@AdrenalineVideos1337]

I should clarify my first comment: Videos that you usually post, like this one, tend to me more demonstrational and practical, with explanations of what is happening in voice-overs. What would be cool is more conceptual, and maybe less practical chemistry. Not sure if that is possible. In physics, for example, its easy to talk about classical mechanics and throw in interesting and quirky (no pun intended) quantum mechanics. Is there some field similar to quantum mechanics in chemistry?

[@lizard5678]

You make the best videos. I have a comment, you said air takes long, while I know H2O2 can can be expensive on larger scale. So how about manganate/permanganate, then dropping out the MnO2 and filtering off the CuCl2. Is there a way to specifically extract the leftover ppm's of manganese, like solvent extraction, reasonably cost effectively in case a very pure solution is needed? But for general etching some minor manganese contamination should not hurt. Any Mn2+ should be possible to drop out away from the Cu2+ with extra permanganate, and then the MnO2 recycled into permanganate with baking soda or soda ash detergent fusion in a crucible, then slightly acidifying and filtering the MnO2 again. Permanganate should be just as fast as H2O2, while available/recyclable to people and H2O2 is more difficult to DIY and you have to keep purchasing it. Chromate is another one, maybe better, maybe worse, especially that it likes to form funky precipitates (copper chromate might be insoluble), but permanganate is monovalent and as far as I know it forms few reaction rate blocking precipitates. Then hit it with a torch in a crucible oxygen access to it, and at high temperatures rates of reacting with atmospheric oxygen should be orders of magnitude higher - near room temperature reaction rates double every 10 degrees, so 500 degrees away is a different ballpark. Of course it is more complicated then simple air bubbling, also it requires fuel, so air bubbling might win in the end for large scale, other than having to recover the evaporated lost HCl. And for that, sulfuric acid doped with enough chloride might be better to make copper sulfate catalyzed by copper chloride corrosion.
