Question

Example 1: A solution of metal salt was electrolyzed for 10 minutes with a current of 1.5 ampere. The

weight of metal deposited was 0.685 gm. What is the equivalent weight of the metal.

Ans. : Equivalent weight of metal = 73.44 gms.​

Answer 1

Explanation:

weight of metal deposited =

equivalent weight of metal × I× t / 96500

0.685=E×1.5×10×60 /96500

E= 0.685×96500/1.5×600

= 73.44 grams

(always put value of time in seconds )
