  • Extracting Metals by Electrolysis

    The reactivity series and metal extraction The reactivity of a metal determines how it is extracted. Metals above carbon in the reactivity series must be extracted using electrolysis. Metals less reactive than carbon can be extracted from their ores by reduction. Copper, silver, gold and platinum can occur in their pure form (natively) and do not

  • Principle of Electrolysis of Copper Sulfate Electrolyte

    Jan 05, 2019· In the above process, after taking electrons the neutral copper atoms get deposited on the cathode. At the same time, SO 4 reacts with copper anode and becomes CuSO 4 but in water it can not exist as single molecules instead of that CuSO 4 will split into Cu + +, SO 4 − − and dissolve in water. So it can be concluded that, during electrolysis of copper sulfate with copper
