1.	State the observations at the anode & at the cathode during the electrolysis of –1. Fused lead bromide using graphite electrodes.2. Copper sulphate solution using copper electrodes.
Answer» 1. At cathode silvery droplets of molten lead appear. At anode reddish vapours of bromine are given out. 2. Brown metal copper is deposited at cathode. Cu²⁺ ion is liberated at anode. Colour of CuSO₄ solution (blue colour) does not fade.
