Question

A solution of aluminium chloride is electrolysed for 30 minutes using a current of 2A. The amount of the aluminium deposited at the cathode is _________. [Given: molar mass of aluminium and chlorine are 27 g mol–1 and 35.5 g mol–1 respectively. Faraday constant = 96500 C mol–1]

(A) 1.660 g
(B) 1.007 g
(C) 0.441 g
(D) 0.336 g
