Question

Q

1 At which electrode does reduction always take place?
2 Give the half-equation for the reaction at the anode, during
the electrolysis of these molten compounds:
a potassium chloride b calcium oxide
3 Give the two half-equations for the electrolysis of:
a a concentrated solution of hydrochloric acid, HCl
b a dilute solution of sodium nitrate, NaNO3
c a dilute solution of copper(II) chloride, CuCl2

Answer 1

For question one I believe the answer is at a cathode is where the electrode has reduction.
