When a current of 10 A is passes through molten AlCl3 for 1.608 minutes. The mass of Al deposited will be [Atomic mass of Al=27 g]:-
  1. 0.09g
  2. 0.81g
  3. 1.35g
  4. 0.27g

Solution

Given data :-

Current = 10 A.

Time = 1.608 min=96.48 s

Atomic mass of Al=27 g/mol

Oxidation state of Al=+3

Mass of aluminium deposited = Atomic mass ×time×currentF×valency factor

Mass of aluminium deposited = 27×96.48×1096480×3=0.09 g

Hence, the mass of Al deposited will be 0.09 g.
