Question

During the electrolysis of copper sulphate solution with copper electrodes, how many coulombs of electricity should pass to oxidise half gram atom of copper to Cu2+ ions?
  1. 96500
  2. 48250
  3. 193000
  4. 95600

A
95600
B
193000
C
96500
D
48250
Solution
Verified by Toppr

1 gram atom of copper will require 2 faraday of electricity to convert into Cu+2 ions.
CuCu(II)+2e
Half gram atom of copper will require 1 faraday of electricity to convert to Cu2+ ions.
1 faraday = 96500 coulomb charge
