Statement 1: When acidified zinc sulphate solution is electrolysed between zinc electrodes, it is zinc that is deposited at the cathode and no H2 gas is evolved. Statement 2:The electrode potential of zinc is more negative than that of hydrogen as the overvoltage for the H2 evolution on zinc is quite large.
