A 4.0 M aqueous solution of NaCl is prepared and 500 mL of this solution is electrolysed. This leads to the evolution of chlorine gas at one of the electrodes (atomic mass : Na = 23, Hg = 200; 1 Faraday = 96500 coulombs) (2007)
If the cathode is a Hg electrode, the maximum weight
(in g) of amalgam formed from this solution is
- 200
- 225
- 400
- 446
Answer
(D) 446
