Question

Why do we add a few drops of dilute sulphuric acid to copper sulphate solution during electroplating?

• A. To increase the temperature of the solution
• B. To increase conductivity of the solution
• C. To decrease acidity of the solution
• D. To decrease conductivity of the solution

Answer 1

The correct option is B To increase conductivity of the solution

Electroplating involves the process of electrolysis. It works on the fact that solutions conduct electricity. We add a few drops of dilute sulphuric acid to copper sulphate solution during electroplating to increase the conductivity of the solution.
