(Assertion - Reason)
The following questions consist of two statements.
Statement I: When acidified zinc sulphate solution is electrolysed between zinc electrodes, it is zinc that is deposited at the cathode and evolution of hydrogen gas does not take place.
Statement II: The electrode potential of zinc becomes less negative than hydrogen as the overvoltage for the hydrogen evolution on zinc is quite large.
