Question

The atomic weight of al is 27. When a current of 5f is passed through a solution of al+++ ions, the weght

Answer 1

Answer:

Weight Deposited = 45g

Explanation:

We Have :-

Weight of Al = 27g

Current = 5F

Solution of Al⁺⁺⁺⁺ ions

To FInd :-

Weight of Al deposited

Solution :-

Al³⁺ + 3e⁻ ⇒ Al

$Eal=\frac{27}{3} \\\\= 9\\\\Wal = Eal * Number\ of\ Faradays\\\\= 9 * 5\\\\= 45g$
