Two Faraday of electricity is passed through a solution of C u S O 4 . The mass of copper deposited at the cathode is: (Atomic mass of Cu = 63.5 amu)
Options
- A127 g
- B0   g
- C63.5 g
- D2 g
Correct answer
C. 63.5 g
Step-by-step solution
Cu + 2   +   2 e -   →   Cu 2 Faraday charge deposits 1 mol of Cu, or 2   F ≡ 2   Equivalents   of   Cu Mass of Cu deposited = 2 × 63 .5 2 = 63 .5 g
