In this chemistry experiment video, we take you step by step how to make elemental copper metal from aluminum foil and copper sulfate, and explain all aspects of the procedure & chemical reaction in detail.
This experiment ranks #1 in our list of home chemistry experiments, because of the ease of its procedure, ease of getting the necessary materials, dramatic results, usefulness for future experiments, and lack of corrosive acids or bases used.
Because copper sulfate is toxic, it must be handled by adults only and stored in a place secured from kids. It is important copper sulfate is not ingested, inhaled or in contact with the skin.
Chemical reaction: 2Al + 3CuSO4 → Al2(SO4)3 + 3Cu
Expected yield of elemental copper is 63.55*(50.0/249.68) = 12.7 grams.
After 2 days of drying, we ended up with 12.65 grams of Cu, for a fantastic yield of 99.6%.

All questions in the comments will be answered. Let us know what your favorite chemistry experiment is, and thank for watching!

@BillAdams001 7 месяцев назад

I've always had a love for inorganic chemistry and non-biological carbon chemistry. However, gourmet cooking is a great way to apply chemistry and especially organic chemistry. Neat experiment converting aluminum foil to elemental copper.

@R462venom 3 года назад

I did a similar thing with Copper Sulphate and Zinc Oxide. I love displacement reactions! Feels like transmutation.

@ChemTalk 3 года назад

thanks Aelios, we love them too! We have a few more planned with interesting metals.

@alienrocketscienceshared8454 6 месяцев назад

I would think with your experience you would know what the NaCl does in the reaction. Count the electrons in the reaction vessel and consider the reactivity of chlorine together with the rectivity series of metals. Copper is the least reactive of all the metals involved, so it is left behind. Sodium is the most reactive, so it creates a side reaction where HCl is created. It is with this side reaction where aluminum and copper trade places in the solution.

I love this reaction it was my favorite early on! I'm re doing this as I need copper powder for stabilizing methyl iodide a bit. Great video!

@davidsmith4467 Год назад

I'm curious. if you used Epson salts and electrolysis with a clay pot barrier, and using copper attached (sacrificial) electrodes to manufacture copper sulfate. And then reversed to results as you have done, what would be the net loss of copper?

@generalingwer4341 10 месяцев назад

Very nice video.i may try that to source my copper for copper acetate.aluminium foil being more abundant at times than actual copper.

@thescienceboy9559 2 года назад

Hi, Thanks for explaining the process in great detail and showing the full process till the end. I have one question, Copper Sulphate is highly toxic when poured down the drain so, is the aluminum sulphate generated and all the other waste products safe to be drained down? I will be doing some electrochemistry and basic reactions with it and I am quite worried about copper sulphate waste. Is this method a good way to dispose waste solution of copper sulphate? I would appreciate some opinions and ideas

@ChemTalk 2 года назад

Your welcome! Aluminum sulfate is the only "waste" and it is very safe to pour down the drain. For copper sulfate solution, you can simply save it for more cool copper chemistry experiments.

@Lawtonfl 3 года назад

This is very interesting, does anyone have a proposed mechanism for why the NaCl allows the copper sulfate to bipass the oxide layer?

@ChemTalk 3 года назад

Great question! The micro-thin oxide layer imparts remarkable resistance to aluminum. The problem with trying to bypass the passivation layer (oxide layer) of aluminum is that it repairs itself very quickly. Yet, chloride is somehow able to do it. Several theories have been proposed why the chloride ion has this effect, but most have not help up to further testing. So even though this has been thoroughly studied, there is no consensus. All that is for sure, is that the chloride ions attack the oxide-layer, penetrate it and somehow reach the oxide-metal interface.

@godfatherofdeathmetal1967 3 месяца назад

Can these be mass produced

@dragonslayer7027 2 года назад

16:00 i suggest getting actual filter paper (i dunno what its chemically called or wtvr), but i did the same experiment to extract the Aluminium Sulphate, and the filter paper from my lab did the filtration in one go, making the solution clear as water (possibly slightly milky). it goes a long way when conducting experiments for your IB IA's and Extended Essays and just saves you a lot of time!

hi i need ur help i tried to make some cu sulphate by using electorlysis copper in h2so4, bu t i dont realized it was ALUMINUM COPPER COATED WIRE not pure copper and my mistske i used too much ampere@ 12 V from dekstop psu and solution become vigorously reacted till next morning even whrn i unplug cord, what do you think then reaction it was? can i recover my copper as powder?

@ChemTalk 2 года назад

Aluminum will react vigorously with sulfuric acid to produce aluminum sulfate. You need to react the copper with hydrochloric acid and hydrogen peroxide.

@InternetFiend68 14 дней назад

just add nacl to copper sulfate then add aluminum foil, the reaction would be much much faster

@mountiedm 11 месяцев назад

I think copper sulphate is one of the least problematic chemicals you'll run across. It's often found in child chemistry sets and cat litter. Yes, it's a chemical. There are plenty of chemicals that can harm you. It's why I don't make spaghetti with USB cables.

@somi6235 3 года назад

Hi, is it possible to torch it to see the metal?... Thnxs

@ChemTalk 3 года назад

Hello So Mi! Can you explain the question?

@BeastM140i 3 года назад

Yes. When you torch the copper metal you’ll see a lovely green and blue colour in the flame due to electron excitation :)

@somi6235 3 года назад

Does the heat in the powder makes apear the metal?

@tlhologeloselapa3043 2 года назад

Hi. I hope you're well. We did this experiment at my school. We added CuSO4.5H2O to H2O and we also added HCl instead of NaCl. Can you please help me with the balanced chemical equation...Do we also include the water and HCl used and the H2O released?

@tomfrederick6083 Год назад

Does the amount of copper metal realized exceed the value of the constituent components used in the experiment?

@tomfrederick6083 Год назад

Actually I think I answered my own question. Bags of copper sulfate on Amazon ar right at the same price per ounce on the market; $0.23 per ounce. There is one bag that is selling for just over $0.20 per ounce. It would take a lot of material to make it worthwhile. If it could be obtained at wholesale prices then I should think that would be quite worthwhile.

Burn copper powder and sulfur, or react copper sulfate with sodium sulfide

hi Katie, good question. Yes any waste from this experiment can be disposed down the drain with plenty of water, or in the trash. We do suggest the people keep the copper powder in a vial or small jar/bottle for future experiments.

@Jkauppa 2 года назад

its not the copper penetrating, its the removal of the oxidation layer, you could try baking soda instead of salt, you made an electrolyte from the aluminium and copper sulphate

@Jkauppa 2 года назад

the reactive part is the aluminium, it takes the initiative, if its exposed to the sulphate, this can be used as a battery chemistry
