Question

Current of 5.0 ampere flowing for 0.5 hour deposits 3.0489 of a metal at cathode. Calculate

the equivalent weight of the metal. [1 Faraday = 96500 Coulomb]

Ans. : Equivalent weight of metal = 32.81 gms. ]​

Answer 1

Explanation:

By using formula -- weight deposited = E ×I ×t / 96500

E = 3.0489 × 96500 / 5 × 0.5 × 3600

= 32.81 grams
