I don't know about the EU now that we here in the UK have committed economic suicide but 37% nitric acid is available here in hydroponic shops as 'Dutch Pro pH Down'. I was quite surprised when I bought some for my errr... Tomatoes... and discovered that's what it was. I was expecting phosphoric acid.
Every single video like this is:" you just need simple household materials. Sugar (me: got it!), distilled water (me: got it as well!), the horn of a manatee (me: well fuck me)"
This reaction is left-shifted so it would accour really slowly and with poor yield or wouldn't at all, witch is what happend, because there wasn't any copper oxalate percipitating out. U can calculate this knowing Pka values and also knowing that stronger acid reacts with stronger base producing weaker acid and weaker base. H2C2O4+CuSO4=CuC2O4+H2SO4 1,27 -3 1,27 -3 Strong Ph that you got was propably from concetrated oxalic acid, beacuse.. it is preaty strong carboxylic acid. And so this violent reaction with sodium bicarbonate, also characteristic for oxalic acid. Much better way to obtain sulfuric acid and also really cheap, is to thermaly decompose FeSO4 iron(II) sulphate(VI) and dissolve formed sulphur trioxide and dioxide in distilled water. 2FeSO4=Fe2O3+SO2+SO3 Thats how alchemist were making sulfuric acid back in the days. Anyway, good luck with your future experiments!
Interesting method, I never heard of this! May be convenient for small amounts. However, one can still buy 15% (or 14.9%) H2SO4 in the EU, often sold for lowering the pH in swimming pools. The issue is that it typically comes in at least 5 liter canisters.
@@tobias_cz8719 As a hobby chemist, one may simply have no use for 5 liters of sulfuric acid in the lab, and the big canister may be in the way. There are also not many everyday/household uses for sulfuric acid where one can use up the 5 liters. The only thing that comes to my mind is: It sounds stupid, but H2SO4 is a marvelous toilet bowl cleaner, and since there are professional grade drain cleaners with >90% H2SO4, this must be OKish for the plumbing and the environment. But don't overdo it, about 50 ml of the 15% acid are enough. I don't see many other uses. This is in contrast to e.g. hydrogen peroxide. I bought a 2.5 liter canister of 11.9% H2O2 (highest concentration available to the general public in the EU) mainly to get rid of a large coffee stain on a carpet. It worked perfectly for this, but I had more then 2 liters leftover. I started putting some into the washing machine and love it, gives the machine and the laundry it a nice clean and fresh smell. And when it was empty, I bought the next canister just for the laundry.
Find a few like minded friends and split the cost and time distilling to the azeotrope . Everyone gets an equal share of the product and nobody ends up having to store a ridiculously large amount .
@@eicydee3212for a lot of chemistry things, it's desirable to have the higher concentration stuff, and it's also just more convenient to have a lesser amount of a higher concentration in terms of storage. Thus you distill it down and end up with less than a liter.
A better way is to electrolyse copper sulphate using lead metal anode and copper cathode. This route wastes precious nitric acid and not efficient at all
you dont need to make oxalic acid you can just buy it since its common and cheap in my country it's around 5$ per kilo but if you have access to sulfuric acid drain cleaner theres no point in making it from oxalic acid and copper sulph. you can also take battery acid and boil off the water and you will be left with concentrated sulfuric acid.Copper sulphate electrolyse isnt efficent you need a power supply you need to have an lead dioxide anode and need to wait for very long time to make small amount of the sulfuric acid
@@polishnope5609 you don't need lead dioxide electrode. Just use lead metal and the speed of acid production by electrolysis depends on how much current you give to the cell. You should not care about cell electrical efficiency in this case. It's also the cleanest method if you don't have Sulphuric acid available like in Europe.
bruh you can buy oxalic and copper sulph do the reaction, distill it concentrate it its way faster and can be done better on bigger scale, i used nitric because i didnt have oxalic on me rn
Battery acid grade H2SO4 (32% by weight) still available here (Romania). Also HCl (32%)and even 69 % HNO3 (sold as lime scake remiver for aluminium pipes)
@@NilaSpeaksLoudlynope, you NEED nitric acid, it literally cuts up the sugar molecules until oxalic acid.. you cant do that with HCl but you can make HCl from oxalic acid
Lol this videos comment section is a hidden gem of finding amateur reagents in europe (even better than what i found on sciencemadness lol). Good video aswell 👍
I really appreciate these videos because if people will be making these dangerous chemicals either way, they might as well do it in the way that puts themselves and the people around them in the least amount of risk
People would not have to make them if we didn't illegalize the sale in the first place. What government sane in their right mind thinks that people are not responsible enough to handle 98% sulfuric acid yet they are responsibe enough to DISTILL it?!?! This regulation is just insane.
*Nitric Acid is banned and can't buy it anywhere* PrussianBlue:"Let's make banned sulfuric acid with nitric acid that is also banned and unavaible for consumers..."
Man, I come here to learn how to make lead-acid batteries and immediately get put on another government list. I just want to make a power wall, not learn how to detonate my hand.
4:20 ... thank your for the video. in my country i cant buy conc sulfuric acid above 15%. so i will buy 1L of 15% and boil of the water AND i will try your method to calculate which one is cheaper. i think your coppersulfate/oxalic acid is more cost efficient tho
try heating ferrous sulphate to decomposition and condensing the vapours Do this in iron or steel flask and use lead pipes in the condenser. Product is super concentrated as it containes SO3 in excess residue is inocuous Fe2 O 3
Yeah, fuming nitric acid puts nitrile and latex gloves on fire in a few seconds, don't use these gloves when handling concentrated nitric acid. It's better to be bare handed, really.
Thank you so much I find sulfuric acid to be a wonderful beverage however it whenever I drink it causes everything in my body to feel likes it burning but still tastes great highly recommend
Hello! I just did this, and my copper oxalate participated out of the solution, but when I run through it a coffee filter it stays in the solution and I cant get it out. Anyone has any tips?
just pyrolyse car tires, hydrogen sulfide is produced which when oxidized(burned) turns into sulfur dioxide or some shit then just bubble that through water. if you add a condenser before the burn chamber you could potentially get a bunch of feul oil too. make sure to put some copper piping or wool after the burn/bubble chambers to catch any unburnt hydrogen sulfide and turn it into copper sulfate. check the walls of pyrolysis chamber every time due to h2s corrosion. unless you use something like glass or a superalloy like inconel it will degrade pretty quick. centifugal compressors seem to work well enough for me but a multistage axial may be more efficient. the reason this isn't the primary method for car tire disposal is because of how dangerous it is, but ive seen you do worse on your channel.
I think it's either water condensing on the beaker, or water condensing on the camera lens. If your camera is in a cooler place, then you move it to an area with high humidity, like the atmosphere in a room with an uncovered beaker with boiling water, then the water in the air will condense on cooler surfaces, such as a cool camera lens.
@@GRBtutorials That makes sense too. I'm more skilled at chemistry then recognising edited photos. I'll defer to your judgement there. But I'm curious about how you can tell it's edited? I have seen my reflection, when I took a photo of my new cooking pan, which showed that I was not wearing pants. So I've seen that reflections in photos can be problematic. I just don't know how to edit a photo to intensionally add blur.
Hello, dear sir. I don't know your name or even your origin, but it's clear to me that your spoken English has a somewhat frenetic and incomprehensible inflection. This will most likely be due to the fact that you speak too quickly without adequately pronouncing a single word, thus risking biting off more than you can chew. You should realize that the topic you are dealing with requires absolute clarity and precision as it could compromise the physical safety of some mentally labile element of your audience who is not always aware of the dangers of this type of chemistry, especially if it is presented in a confusing or unclear. Therefore, I kindly urge you to speak slowly, enunciating the words and sentences of the concepts you want to explain. Thank you very much, with my best regards. Dr. G. A. Mereu Lyczkowska
