Question

Amount of electricity required to reduce 0.5 mole of A13+ ions to Al atoms is

A)3 F
B)2F
C)0.5 F
D)1.5 F​

Answer 1

Answer:

d option

Explanation:

As we know amount of faraday required to produce 1mole of ions is equal to its valency

2. Therefore in case of Al it is having +3 charge it means 3 Farady required to produce 1 mol of Al

3. To produce 0.5 mole of farady electricity required = 0.5 × 3 = 1.5 F
