Question

in the electrolysis of sopper sulphate, for the production of one mole of copper, how many moles of electrons are needed

Answer 1

Explanation:

two moles

In CuSO4 solution, oxidation state of Cu is +2. Hence one mole of copper sulphate will require charge equal to two moles of electrons to form metallic Cu. Mole charge = IF. Hence 2 Faraday is required.
