Question

When one Faraday current is passed, which of the following would deposit 1g atomic weight of the metal?
  1. NaCl
  2. BaCl2
  3. AlCl3
  4. CuSO4

A
CuSO4
B
AlCl3
C
NaCl
D
BaCl2
Solution
Verified by Toppr

Gram-atomic weight definition is the mass of one mole of an element equal in grams to the atomic weight

No. of gram equivalents = Weight of substance / Equivalent weight

Now, as the valency of Na+ in NaCl is 1,

Equivalent weight = Molar mass/ valency = Molar mass/ 1 = molar mass.

1 F will deposit only 1 mole (or one gram equivalent) of Na metal.

No. of equivalent weight deposited = molar mass / equivalent weight = 1 gm atomic weight.

Hence, option A is correct.
