Question

What causes an increase in the amount of formation of impurities at a higher rate?

(a) Increase in concentration

(b) Decrease in concentration

(c) Deterioration in the amount of molecules

(d) Destruction in the electrode

I got this question in a job interview.

I want to ask this question from Characteristics of Electroplating Wastes topic in division Electroplating of Engineering Chemistry II

Answer 1

The correct choice is (c) Deterioration in the amount of molecules

To explain I would say: During electroplating process, the amount of molecules plays an important role in the determination of electrolysis of absorbent (water or any other fluid). Thus decrease in the amount of molecules will increase the formation of impurities.
