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 :)
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.
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.
@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.
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?
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.
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.
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).

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