Acidified water is electrolysed by using carbon electrodes. What is produced at negative carbon electrode?

Open in App

Solution

During electrolysis of acidified water, $H^{+}$ ions are reduced to $H_{2}$ gas at the negative carbon electrode (cathode) and hence hydrogen gas is liberated at cathode.

Q. Assertion :When acidified zinc sulphate solution is electrolysed between zinc electrodes, it is zinc that is deposited at the cathode and hydrogen evolution does not take place. Reason: The electrode potential of zinc is more negative than hydrogen as the over voltage for the hydrogen evolution on zinc is quite large.
