Question

One Faraday is the amount of current:

• A. that liberates 1 g equivalent of a metal from its solutiion
• B. 96515 coulomb
• C. that liberates 31.78 g of Cu
• D. that liberates 1/2 g-atom of Cu

Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A that liberates 1 g equivalent of a metal from its solutiion
B 96515 coulomb
C that liberates 31.78 g of Cu
D that liberates 1/2 g-atom of Cu

One faraday of electricity corresponds to 96500 coloumbs of electricity.
It liberates 1 g equivalent of a metal from its solution. For copper 1 g equivalent corresponds to 31.78 g.
This is also equal to 1/2 g-atom.
Thus, one faraday of electricity liberates 31.78 g or 1/2 g-atom of copper.
