The number of moles of electrons required to deposit 1 g1 \mathrm{~g} equivalent aluminium (atomic wt. =27=27 ) from a solution of aluminium chloride will be

Options

  1. A3
  2. B1
  3. C4
  4. D2

Correct answer

A. 3

Step-by-step solution

Al3++3e−→Al\mathrm{Al}^{3+}+3 e^{-} \rightarrow \mathrm{Al} Therefore, number of moles of electrons required to deposite 1gm1 \mathrm{gm} equivelent of aluminium is three.
