Copper(II) acetate, Lead(II) acetate and Lead(II) chloride preparation

[@THYZOID]

That’s nice! What can lead chloride be used for? I’m planning to make a lot of lead chloride from my conc. lead acetate leftover solution (that would otherwise be disposed of) but don’t really have a use for the product.

[@AdvancedTinkering]

Thanks! I want to use them to make cesium lead halide perovskite nanocrystals.

Man I’ve been trying to do this reaction to grow copper acetate crystals but I keep making this paint looking sludge that according to online sources it’s copper hydroxide… My first run was following this crystal growing website steps. I used 250mL of 3% hydrogen peroxide peroxide, 50mL of 45% acetic acid, and 10g of copper bits from Amazon. Within 2 hours or so the solution did indeed turn that nice dark blue but was still bubbling from the copper scraps, so I left it for 2 days. The solution was still dark blue and I put it in a flat open container and left it outside in the sun. The crystal website said that if the solution has white sediment that it’s prob copper carbonate or copper hydroxide contaminants, and that adding more acetic acid would fix it. So I did, I added 100mL extra. 3 days after and the volume is now less than half but now there’s all this contaminated sediment that looks like teal paint and no visible copper acetate at all. For my second run I tried the 50:50 H2O2 to CH3COOH without regard for the difference in concentrations. Using the same amount of copper. This reaction turned light light blue towards the bottom after like 9 hours :| so I scrapped it, no true reaction was taking place, as in, this would prob have taken a week to go to completion. My third run was stoichiometric. As I understand, this reaction is Cu+2CH3COOH+H2O2->Cu(CH2COO)2+2H2O I’m not a noob in chemistry, currently taking orgo I at uni, so it’s not like I’m a noob who saw pretty crystals and wanted to grow them without any understanding. I’m no chemist, not at all, but I know enough to know what’s happening. I’ve read some forums and papers and seen there are other side reactions that could be happening, especially with contaminants. But whatever. Using that, I said “I want 10g of product” and did the math, including using the concentrations of my solutions. Then I saw I would need like 3.8g of Cu so I just multiplied every result by 10/3.8 to use a solid 10g of copper reactant. I got something like 10gCu + 230mL H2O2 + 160mL CH3COOH (not exact numbers, but close enough) I mixed these reactants and within like 5 minutes, I shit you not, within 5-10 minutes my solution turned dark blue like before and there was still fervent bubbling coming off the copper bits. After 2 days I transferred this solution to another flat glass container to let it evaporate, it was great until I saw the white sediment forming… I’ve been adding 100mL of acetic acid every hour, this, according to chemistry forums, will avoid the coupling of copper with hydroxide, and allow the copper oxide to drop the oxygen and bond to the acetate forming my desired product. Every hour I go back and check, if there’s that ugly sediment forming, I’ll add more 100mL, I’m up to like 700mL added extra :| and every time I go back it’s still forming this…. Everyone on Reddit and chemistry forums suggests using glacial acetic acid. I’ve ran the stoichiometry again & figured out the amounts needed, and indeed I’ll need a lot a lot less acetic acid at 98%. I’m not comfortable using this concentration of acetic acid, mainly future storage and disposal wise. But whatever. Some people on Reddit have said they just add a couple of drops of this thing and it sellers everything :| I’m waiting for the glacial acetic acid to arrive along with uncoated copper wiring. I’ll run my next attempt with these. I don’t have hot plates and thus can’t do evaporation and heating the solution outside, and I won’t do it indoors. I don’t know what I’m doing wrong… Is my equation wrong? Do I need stronger hydrogen peroxide? Is it the acetate? Is it the volumes of H2O2 and CH3COOH what are wrong (even at stoichiometric levels)? Any help, anyone, please

[@Impatient_Ape]

Since lead is toxic in even tiny amounts, can you tell us what you did with the filter papers afterward?

[@AdvancedTinkering]

I collected the liquid waste and the solid waste in different containers and brought them to a company that is specialized in the disposal of chemicals.

[@experimental_chemistry]

Nice 'n' simple experiment - great channel! 👍 Love to see the model of Dipse I use, too. 🙂 One little hint (from someone who has also a hard German accent... 😉): please pronounce "the" with a long "e" only in front of a following vocal - otherwise it might hurt in the ears of native speakers...🥴

[@michaelandersen7535]

Nah, it doesn't hurt at all. As an English native speaker, the German accent is quite erudite. Don't worry about how you sound, just be yourself. It's a plus, not a minus

[@experimental_chemistry]

@@michaelandersen7535 OK, that's interesting. And a native speaker can judge it better of course. But what do you mean by "erudite": rehearsed or educated? It is quite possible that the frantic attempt to correct the ingrained error would worsen the speech quality overall rather than improve it. Then leave everything as it is, that's better. I agree.

[@6150RE]

Lead acetate is sweet

[@UltrAgejmr]

Why did you use the copper acetate? Why not dissolve lead in acetic acid with hydrogen peroxide just like the copper?

[@colin351]

You gonna second guess a German about chemistry?

[@tahallium]

probably because that way it would generate lots of harmful and quite toxic mist and droplets that contain soluble lead

[@Berghiker]

Where do you get 25% acetic acid from? I already have 30% H2O2.

[@AdvancedTinkering]

You can just buy it. I used vinegar essence.

[@Berghiker]

@@AdvancedTinkering So vinegar essence is 25%?

Replicate your content in a decentralized platform, like Odysee. Otherwise, it is a matter of time to all this info became lost to censorship.

[@experimental_chemistry]

Look at all the "golden-rain"-videos with lead iodide - none of them has ever been deleted by YT...

[@niksoley]

@@experimental_chemistry good, just take care, your content is too good to be lost.

[@experimental_chemistry]

@@niksoley Thanks for the well-intentioned warning and the indirect praise. I wouldn't be so sad about the "Golden Rain" - it's not my best video, neither in terms of success nor the number of views... However, I do not know of a single case in which a comparable video would have been deleted. And if so, there must have been other reasons. There is e.g. one or the other chemistry KZbinr who swears a lot or uses street language, presents dubious content or opinions. I think that I offer comparatively little reason for this. In case my whole channel disappears one day (which I don't think it will), I've archived all the videos. So I'll switch platforms. Unfortunately, I don't know of any others that offer the prospect of monetization.

[@niksoley]

@@experimental_chemistry you are correct, KZbin is the best in numbers of users and monetization. I’ve seen non chemical channels been blocked, had videos removed or monetization suspended, in witch there were no clear explanation of what directive they infringed. Even huge channels lack a account manager or any type of non standard contact with the company. In therms of business strategy, due to no clear communication with the platform and volatile rules and decisions, I would consider to develop in other platforms in parallel. Regardless of your choice, I am already subscribed and hoping to see your growth :)

[@niksoley]

By the way, just sharing one case of chemical channel that had great growth because of 1 video about graphene. If you have knowledge and/or interest in anything that is the hype, take advantage of it! After that, your others videos will have the attention they deserve. Another point you may consider is well explained is a video of veritassium about clickbait: kzbin.info/www/bejne/iWPbeY2GfZqGpMk
