The electrolyte should contain positive ions (cations) of the metal to be deposited. These cations are reduced at the cathode to the metal in the zero valence state. For example, the electrolyte for copper plating can be a solution of copper(II) sulphate, which dissociates into Cu cations and SO 4 anions. At the cathode, the Cu is reduced to metallic copper by gaining two electrons. WebJun 10, 2024 · Faraday's First Law says that the amount of metal plated onto the cathode is proportionate to the current, so it should be that a higher current= more metal plated onto the cathode (I assume). And from Ohm's Law, a higher current= higher voltage so (by syllogistic reasoning) a higher voltage should give you more metal plated onto the cathode. cykel touringWebAt the cathode If you electrolyse silver nitrate solution using silver as the anode, silver is deposited on whatever material the cathode is made of as you would expect.
