  • What isn't legal these days

  • What did I just watch.

  • this is illegal you know.

  • That blue copper solution has to be copper sulfate, not sulfide

  • kinda surprised you wore golves for just a couple drops of h2so4. I did the oposite and used current to make the solution of cuso4 from just a cu electrode and sulphuric acid in a jar and hook up the old copmuter power suppy and shazam, it is a time consuming mess of crystilation and acid. I used WAY more h2so4. prob close to a litre. I got some cuso4 to mess around with and plate stuff. and it only cost me time and a few cents in electricity. and when ya boil down you get yours acid back :)

  • Whats the molarity of the sulfuric acid? And is there a simpiler way to do this without using electrolysis?

  • You don't need high voltage, but rather high current. So long as you're above ~.7V (potential of a Cu+Fe cell), you can get the reaction to run in reverse.

  • A 1.5 volt battery is fine, because the reduction potential of copper is less then 1 volt, and even a Zinc/Copper battery can only produce 1.1 Volts about, which is when zinc is oxidized to Zn++ and Cu++ is reduced to Cu metal. So running that in reverse would TAKE 1.1 Volts to oxidize copper and reduce Zinc.

  • I did this, but instead of a normal battery, I hooked it up to my car's battery. It turned coppery in half a second and started growing crystals!

  • @nickbhalo I declare you the Chuck Norris of galvanisation!

  • @tmafkap Thanks for the honor!

  • can you do brass like this way????

  • Thers no difference between 9V, 150V or 100000V, all that matters is that its above around 2V and has a high ampere, more voltage doesnt speed it up, you need more current

  • i guess ur power supply was current limited? because there is no way u used 150 volts on that with out drawing a bunch of amps and boiling the solution

    so u dont need taht many volts cuz another voltage can deliver the same amps

  • 150V of direct currect? Wow, thats not gonna exploded in my face or anything, does it? 12 hours in that amount of voltage, I'de figure the coin should have been a serving plate by now.

  • how i get sulfuric acid

  • Can you use copper acetate instead of copper sulfate?

  • can you just let it sit in copper sulfate?

  • Do you really need 150 volts? It seems very excessive for somthing like this.

  • you can use a 6V battery and vinager instead of copper sulfate.

  • @Kutnix that's an practical solution and not harmful.

  • can u use aluminum foil besides the coin?

  • gay

  • 20 volts good?

  • can we use 9V of cell?

    it's difficult for us to find a power supply which supplies 150V.

  • @RonKei26 Im not sure, I didnt even know this would work when I tried it, It could work just may take long time

  • @Basco36 you can use 3 volts. depends on your solution and amps. volts arnt the issue with electro plating. i plan to copper plate my shotgun soon :)

  • @RonKei26 actually 150 dc is REALLY easy to get. you only need one item, A bridge rectifier. Take the the two leads from the wall and attach it to the markings where is says AC. on the DC output it should be around 150v.

  • @RonKei26 yes you can. all you need is more then (i think) 5 volts. 6 if not. but yes, it will work. the current is really what increases the rate of reaction. Ive done similar experiments what 12v, 50 amps, and it took a couple minutes. but then ive also tried 50,000v at 10ma. though i only had it in for a few seconds because i didnt wanna burn out my HV power supply, it was too slow for any visible reaction to occur.

  • how long will it take with 12v ?

  • Do you really need 150 volts?

  • @bobbysam232 Im thinking the more power the faster it is plated

  • i was wondering, how thick is the new copper layer and how easy it is to scrape it off?

  • copper sulfate is so much fun. You can buy it cheap.

    root destroyer is one

    You can put nails or zinc in it and it's plated instantly (but it flakes off.)

  • How mucha V do you use? and..hoy much Amp do you use? thanks!

  • in the video; 150 v DC is passed thru the quarter.

  • A 6v lantern battery is enough. You don't need 150v

  • Is that concentrated HCl? Beacuse it's yellowish color.

  • HCl is Muriatic Acid.

  • Basco, are 150 volt? or 1.5 volt?, i have tested with 4.5 volt (cell phone charger) but the copper coat vanish when i try to clean the excess

  • higher voltage give a better bond to the plating.

  • As great idea as that may seem, the quarters still have the date on them and the bidders could confirm that the U.S. mint never made copper quarters during that year (that's on the quarter).

  • any ideas on synthesizing silver nanoparticles using electro chem methods? We've been reducing silver ion from AgNO3 solution using UV light. (not sure how the reducing is taking place though) either the electron is being taken from NO3- to for NO3 radical, or its interfacing somehow with the water. I do know the pH is changing, and no mass is lost by gas effervessence. any ideas?

  • sulfiric acid smells so bad

  • sulfuric acid has no smell when it pure

  • where do u get it? all i could find was muriatic acid.

  • @flagman57 maturiatic acid is pretty much the same thing

  • lol i thought muriatic acid was HCl acid

  • Comment removed

  • @flagman57 wait nvm

    hcl is hydrogen chloride

    hydrogen chloride is a gas

    to make hydrochloric acid you need to run hydrogen chloride through water

    after you do that the water will be hydrochloric acid i believe

  • Why would you want to put this in a soda machine? My only guess is that it makes it seem heavier and thinks its 2 quarters or other.

  • A lower voltage would most likely work better here - usually 1.5VDC is all that is required and results in a more even coat.

  • cool but your hcl dosn't look very clean

  • Is CuSO4 nescesary for this? Is this coin plated by copper from foil or copper from CuSO4?

  • the copper comes from Cu2+ ions in the solution :-)

    my cell doesn´t work though, the cathode gets coated with copper oxide :-(

  • Try increasing the concentration of your CuSO4. You get the black stuff when you have an absence of Cu2+ ions, so the electricity ends up splitting the water and releasing H2 gas.

  • Nice! i've got to try this for my channel.

  • It's nice to see you back, Basco.

    You could make a "cleaner" procedure usink two beakers (one for copper, the other for coin), and connecting then with a salt link... salt link is simply a piece of paper or fabric soaked in salt water; a more fancy one is made with KCl saturated-jello in an U-tube.

  • its great you're posting again.

  • what does D.C. stand for?

  • Direct Current (like the power supplied from batteries with static [non-changing] terminals like [-] negative and [+] positive.

    Wall power (supplied from an outlet) is alternating current, with terminals normally designated as [~] and [~] as well as an earth ground. In alternating current, the polarity of the terminals changes at a rate of about 60 Hz in the US (60 times per second) from positive to negative or vise versa (as the flow of electrons is changed).

  • can you plate it with other metals aswell?

  • ya.

  • I demand oxidized rhodium quarters ASAP! A bit expensive I'd guess...

  • how???

  • This process, called metal plating

    Googel It and you will know How.

    5*****

  • Now that is cool!

    5 stars!

    and first!
