Question

Calculate the amount of electrolyte required for electroplating 50 grams of magnetite.

(a) 60 ml

(b) 70 ml

(c) 80 ml

(d) 100 ml

The question was posed to me by my school principal while I was bunking the class.

Query is from Electroplating Baths in portion Electroplating of Engineering Chemistry II

Answer 1

Correct option is (d) 100 ml

For explanation I would say: We know that the amount of electrolyte required for electroplating metal is twice the amount of metal. Thus here since 50 grams of magnetite, the amount of electrolyte required is 50 x 2 = 100 ml.
