Question

One Faraday is the amount of current:
  1. that liberates 1 g equivalent of a metal from its solutiion
  2. 96515 coulomb
  3. that liberates 31.78 g of Cu
  4. that liberates 1/2 g-atom of Cu

A
that liberates 1 g equivalent of a metal from its solutiion
B
that liberates 1/2 g-atom of Cu
C
96515 coulomb
D
that liberates 31.78 g of Cu
Solution
Verified by Toppr

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.
