During the electrolysis of molten sodium chloride, the time required to produce 0.10 mol of chlorine gas using a current of 3 amperes is
  1. 55 minutes
  2. 110 minutes
  3. 220 minutes
  4. 330 minutes

Solution

For 1 mole of Cl2, 2F electricity is required.
∴ For 0.1 mole of  Cl2, 0.2 F electricity will be required.
∴Q=I×t
or, t=QI=0.2×965003×60≈110 minutes.
