Dissolving $1000 of Platinum to Make $6000 of Chloroplatinic Acid for Professional Use

In this video we dissolve a one troy ounce platinum bar in aqua regia and then process that and make ampules of chloroplatinic acid.
My previous videos on dissolving platinum:
• Platinum Bar Dissolvin...
• Make Purified Chloropl...
First we meticulously clean the beakers and condensing flask by first pyrolyzing them in an oven at 500 celsius for 24 hours. This destroys any residual organics. Then we boil dilute aqua regia in them to remove lingering inorganic residues. One troy ounce of platinum is then dissolved over 2 days using aqua regia in that beaker. Once it's dissolved it's boiled for another day to decompose any remaining nitric acid. The chloroplatinic acid solution is then evaporated down to less than 80mL and carefully pipetted into ampules. The ampules are then dried in mason jar desiccators over several weeks before finally being flame sealed. To ensure safety the ampules are soaked in sodium metabisulfite solution to remove any possible contamination of chloroplatinic acid and then labelled. They are vacuum sealed into plastic bags for shipping

As a physicist, I have to take my hat off to chemists. Yes, it is "just quantum mechanics of the last electron orbital" but it is also sooo much more. There is art, there is (immense, and I do mean IMMENSE) skill. Yes, in fundamental physics we do ten-decimal-places precision, but we mostly do it by trowing 10-digit sums of money at it (or more). For a 1% precision in physics you'd need to spend 5-6 digits, at least. And here we get 1% with the most expensive equipment being a $1-2k scale. Well, that and the training and skill of the experimenter. Who is worth his weight in gold. Probably literally. And I mean properly literally.

To be fair, any large scale physics experiment doesn't only need a shit ton of money, but also hundreds or even thousands of people working in it. It's just a different scale, if you calculated the cost of the LHC per physicist, engineer and chemist who worked on it, it would be much more efficient in terms of accuracy per dollar per person. You could do some physics experiments at home for a couple hundred of dollars and get results of the same order of precision as a home chemist purifying their product to 99%+

[@seeigecannon]

Pro tip for precision balances, it won't quite apply to the one you are using, but if a more precise balance is used it is important: Get an anti-static gun (we use a Milty Zerostat 3). When handling glassware it will accumulate a static charge. When you put the glassware on a balance and close the door the reading will take a very long time to settle and will drift because the static field is changing which changes how much weight it is applying to the balance. Hitting it with the anti-static gun drains the static field away and allows the balance to settle faster and reduces drift by a lot. Some of these balances also have an option for either an automated electric ionizer or a pellet of Americium (same element used in ionizing smoke detectors) to emit alpha radiation to drain the static field. I was actually a bit upset when my manager finally told me about this (I thought the gun had something to do with the HPLC vials lol) because I spent a day trying to figure out what was wrong with our balance. When I would put a volumetric flask on it the reading would just keep on drifting. After a few minutes it would be a couple mg off of what it used to read. I was putting test weights on it, and even left a test weight overnight, and the readings were always perfect. My boss then told me about the effect a static field has on the glassware and showed me the anti-static gun. Sure wish he told me about that a year earlier lol.

[@NurdRage]

whoa cool, thanks for the tips!

[@edwardscott3262]

A fun fact about those anti static guns. They often use polonium. The same radioactive isotope the Russians used in that guy's tea. They need to be replaced fairly often because of it. Which makes polonium much more commonly available than people think.

[@seeigecannon]

@@edwardscott3262 these particular static guns use a peizo crystal. Instead of striking it like a grill ignitor it has a huge lever arm that just flexes it. The anti static blowers I have seen in the past also use Americum as an alpha emitter.

[@seeigecannon]

@@edwardscott3262 I just looked this up, and it turns out I was wrong. To my surprise, some air gun static eliminators do actually use Po-210 that is glued onto the surface. You can also get strips of Po-210 for analytical balances. Thank you for allowing me to learn something.

[@D-Vinko]

@@seeigecannon Polonium is actually very common in these static guns. Polonium only really releases Alpha particles, which can be stopped with a good sheet of paper, or a few centimeters of air. This makes it extraordinarily safe when only externally exposed. Those alpha particles are actually what causes it to be "Anti-Static," alpha particles will react with negative ion charges that are accumulated from free electrons like the ones you accumulate from the difference in charge between your head and your feet, neutralizing them, and "killing" the static charge. The Russians got Litvinenko by getting him to ingest the polonium. Inside of his body, the alpha particles could wreck havoc on his organs, without protection from the air and his skin. Otherwise you could (theoretically) handle polonium bare handed, though that's not advised, because if you ingest it, you're Alexander Litvinenko.

[@stevengill1736]

I worked at a company that made Adam's catalyst (PtO2) that was used for hydrogenation. We started with an ounce of platinum wire (about $300 back in 1977) and as you described dissolved in in aqua regia, then precipitated the ammonium salt with NH4OH. This was mixed with sodium nitrate and fused - after copious clouds of NO2 were evolved, you're left with PtO2 in sodium chloride, which is crushed and dissolved in water. The Adam's catalyst is filtered, washed and dried. You can use it as a catalyst until exhausted, then dissolve it in aqua regia all over again. We did that a lot. So easy to make, can't imagine how it costs so much. I'm astonished that platinum is still so cheap....leas than a thousand an ounce, which considering how much of it comes from Russia is pretty amazing.

There's a lot of odd amalgams that can form this way, too. In the same way that gallium will destroy aluminum via amalgamation, so too can some other odd combinations of metals brought in contact. Some don't seem to have done anything right away, but have significantly weakened one or both pieces.

My theory is that they are optimizing formulations of their catalytic process. In that case I'd want stoichiometric precision and a low price from my supplier. Presumably, your single batch process yields consistancy across your ampules. They can assay the quality of the first ampule they use so they only pay once for trust. With S-A they pay for that trust with every ampule.

I really like this video as it shows that being a chemist is way more than just knowing the reactions and combining chemicals. The amount of preparation before doing a reaction or experiment takes way longer than the actual reaction itself. This video clearly shows that drafting protocols (and getting second opinions on protocols), preventing impurities by prepatory cleaning, Calibration and calculations all cost alot of time before doing any reaction. Additionally, some problem solving is shown (cleaning ampule necks). Maybe its not flashy, but it portraits really well what a chemist does. I can't imagine to do this myself if I also had to video it all 😅.

[@superdupergrover9857]

In my experience selling automotive parts, using vinyl labels instead of paper is a smart move. You do want to make sure that the ink/toner is covered by a layer of clear plastic, as some solvents can dissolve the ink. NEVER use ribbonless heat transfer paper, that stuff dissolves just by looking at it sideways. IDK why that is even legal to make receipts out of. Also, don't trim the bags so close to the heat seal. The extra border serves to protect the seal and allows you to reseal the bag if for whatever reason you need to do so.

25:40 This is how DNA and Plasmids are sold for Microbiological work.

[@NurdRage]

Truly amazes me how biochemists handle their 1ug samples.

[@jameskolby]

I love seeing a professional from a field I'm not familiar with sharing the little tricks and processes of their work! I would never have thought that the bulbs on the ampules indicate that they had sealed before they cooled.

[@NeneExists]

I don't think you should underestimate the amount of trust you've developed by documenting your methods and the care you take. If I needed chemicals, I'd definitely think of buying Nurdrage brand, and I'd definitely rather give the money to you than Sigma bloody Aldrich

[@NurdRage]

hmmm.... if i see more comments asking for it, i might do a second run for public sale. we'll see.

[@NeneExists]

@@NurdRage just to say though, I don't need chloroplatinic acid in particular, I'm just saying that you have plenty of trust to trade on.

[@antozon5070]

Really loved the clean and calm approach here, great work! I wish more people would do something like this rather than go for the most dangerous or toxic or stinky thing they can think of.

[@srikgamer1584]

i dropped my joint and became sober because nr posted

[@Haplo-san]

I am not your friend but I appreciate them. If your "friends" doesn't appreciate them, change your friends. This is great work.

[@shemmo]

your videos are a gem

[@ThunderChickenBucket]

So cool to see your work flow and project management, which is definitely not something I thought I'd ever say! I also absolutely love the over-the-shoulder view of an expert at work. Once again, you do a good service to young and becoming scientists everywhere, as well as crotchety hermits like me who've lost their edge...

[@CsendesMark]

5:10 it is because Platinum is heavier than feather 😁

[@nomcopterlabs]

So meticulous! Impressed with your patience and precision and I had fun watching the process.

[@ashenblaze2898]

Been a fan of your channel for a long time and throughly enjoyed watching this video. Apologies for being a downer but those plastic bags you used at the end are actually water permeable. They used for food owing to the low oxygen permeability. I work in the electronics industry and frequently deal with expensive parts that have to be stored at sub 5% RH to avoid potential damage at solder reflow temperatures. I've tried using freezer bags to vacuum seal parts before but had dessicants become saturated and indicator cards set off despite the bag remaining under a vacuum seal. It baffled me for quite a while. The foil bags you can buy for storing moisture sensitive electronic parts are what you want if you need to keep stuff properly dry long term.

[@NurdRage]

I'll definitely upgrade my bags for the future! Thanks! I suppose it's not too bad for this case since the bags are a backup for the ampule. Not the primary container. If the ampule breaks the bags still buy time and protection until the chemicals can be properly recovered and transferred to a vial. But for extra protection I should absolutely get better bags. Thanks for letting me know!

[@ashenblaze2898]

​​@@NurdRageno worries, you'll certainly be fine in this case with the glass and well padded tins. I've only had problems when trying to use freezer bags as the primary layer. I can't remember the exact rates of water permeability but there is a table online if you wanted to calculate how much water would be absorbed over a period of time. On the other hand though I'd pick food grade bags will introduce less contaminants in the event of an ampoule breaking. Industrial stuff isn't usually very clean :) Possibly the best is to double bag with a dessicant in the outer layer??

[@BskFpv]

i have no idea why i watched this but its very interesting, i guess its just fun watching people do what they love

[@MrItsthething]

I work in a plant that makes this material on an industrial scale. I've worked with it a handful times in the lab. Very cool to see someone else doing it.

[@theMedicatedCitizen]

Your channel is the best way to end up on a government watch list!! Thanks for 10 years of science!!

[@josuelservin]

I'm here mainly for the entertainment value of seeing an expert do what they specialize in, I do appreciate the the learning of lab technics and procedures, witch can easily be ported to my own work and hobbies, so thank you for taking the time of producing this videos.

[@computersales]

As a packaging enthusiast I love how much effort was put into packing them.

[@sirflimflam]

Hey NurdRage, I've been watching you since the early 2010s. It's kinda crazy how much time has passed. Not a chemist, not even a hobby level one, but for some reason your videos are always super interesting and I can't help but watch!

[@yashasvi_handa]

The first time i watched you video was when i was 9 or 10, it was about making glow sticks i still remember man those were the days, still seeing you after these years is a blessing honestly, people like you, kipkay, styropro were the best……

[@KHRONOS2232]

"Those were the days" my man, you are still a child. 😂

[@yashasvi_handa]

@@KHRONOS2232 wow bro, you are so cool bro, you need a medal for this reply? Here have this, be happy. 🥇🎖️🏅

[@Damonnanashi]

Finally, someone on KZbin that makes nice looking ampoules.

[@Misc_Identity]

Since all things are metals at absolute zero, it's amazing to see a physical bar "vanish" in a transparent liquid. Awesome video.

[@chonchjohnch]

Actually near absolute zero, you get Bose Einstein condensate, which is a fascinating material :)

[@user-ql6dt3rr9c]

I just LOVE how you implement precision in your synthetic approaches. So meticulous and thorough. That's why you have always been my all-time-favorite Chemistry KZbinr

[@NastyMick]

A wonderful demonstration of why Chemistry and Science in general can be so expensive. Granted, I'm sure bigger companies have faster ways of doing this, (aka, more expensive equipment,) but all that comes at a cost too, I'm sure. Your attention to detail is inspiring regardless.

[@PhantomGeistCommunity]

This channel is goated, surprised i didnt find this sooner, earned yourself a new subscriber mate

[@terribleterrier1685]

This video is giving me flashbacks of Quantitative Analysis in college. Wonderful technique dude. A joy to watch an expert at his craft.

[@nameismetatoo4591]

I'm not a chemist but I love watching your videos because I always learn something. While it seems obvious after you mentioned it, the evaporation of the solution during transfer to the ampules is something I wouldn't have ever considered to be significant (or at least not significant enough to necessitate a calculation). It's a perfect example of one of those "unknown unknowns" that only someone with experience would take into consideration.

[@Lennhart_DeroW]

Its cool to see some of the differences in the process from the "good enough" for the amateur use and the professional grade stuff.

[@74Gee]

The attention to detail was inspirational.

[@dannap8831]

This kind of precision is called-for in the production of first-surface mirrors. Maybe your friends are using the Pt for that! I would also love to see how this ends up being used. Cool video

[@BrandonConrady]

Holy smokes I remember watching you like a decade ago. Cool to see you're still doing content.

[@esn2455]

I love the quote “since people with money don’t care about the opinions of people with brains”

[@zeromotivation1817]

I was going to say weighing the beaker on an open scale would be affected by micro air currents, I can only assume multiple weighing's would average that out? My next lab (2nd year environmental chem ) is far below the quality shown here, will be to extract, purify and calculate the amount of copper in a given rock sample I have to add my thanks to you for these video, the quality, passion and humour is top notch. ("People with money don't care for the opinions of people with brains").

[@thomasgreen4520]

I would say, they are being used for the reduction of benzaldehyde with ammonium chloride...... Hopefully no communities get ruined. The burden of a chemist, is the hardest burden of all.. love you NR. Been watching you for years. Your a genius ❤❤

[@JamesBakerOhio]

Nice treatment on synthesis and packaging, really relaxing and educational, never gets old hearing the WHY and watching someone practice the art.

[@GIRGHGH]

There are multiple facets to an enjoyable video. I wouldn't say I enjoyed this purely because it's a chemist passionate about his work, it's also because it's interesting seeing a more meticulous procedure. Lots of youtube chemists I watch aren't as careful with their chemistry. Also bonus if I haven't seen the original yet so it's still fresh.

[@josephlieberman3027]

A chemist i was working for one time, needed his old truck to pass the smog certificate renewal test. He looked among his Pt group metals on hand, (he did electrochemical precious metals refining) Im not sure the details but i believe we used ruthenium acid salt solution and sprayed some into the carburetor while running the engine the idea was to end up with a born again catalytic converte.

[@avii2807]

I remember watching and subscribing to your channel when I randomly came across your "Making Nitric Acid - The Complete Guide" video; I was ten at the time I came across it, and now, 12 years later, I'm graduating with my Bachelor's Degree in Chemistry, lived and survived long enough to see you produce your own, albeit commissioned, branded chemicals. Thank you, NurdRage, for being the catalyst in my long journey into this field that is both underappreciated, overlooked, but universally important to everyone. (p.s. I would actually love to buy and see you produce more of these NurdRage merch chemicals at some point in the future)
