Question

Calculate the weight of A l deposited when a current of 5 Faradays is passed through a solution of A l + + + ions, (The atomic weight of A l is 27), 27 g m, 36 g m, 45 g m, 39 g m

MARKS App · Accepted Answer

A l 3 + + 3 e - → A l E A l = 27 3 = 9 W A l = E A l × N o . o f f a r a d a y s = 9 × 5 = 45 g m .
