Question

Copper and hydrogen can each be formed by electrolysis.
At which electrodes are these elements formed?

Answer 1

Answer:

Hence in the electrolysis of an electrolyte, the positive ion accepts electron and is reduced and the negative ion gives up an electron and is oxidized. So Copper i.e. Cu and hydrogen i.e. H2 both formed at negative electrode i.e. anode during electrolysis.
