Question

Which of the following polarization will be influenced by electrolytic agitation?

(a) Activation polarization

(b) Resistance polarization

(c) Concentration polarization

(d) Both Activation and Resistance polarization

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

The origin of the question is Corrosion Principles in portion Corrosion Principles of Corrosion Engineering

Answer 1

Correct choice is (c) Concentration polarization

Explanation: Concentration polarization refers to the electrochemical reaction that is controlled by the diffusion of ions in an electrolyte. With an increase in the velocity or agitation of the electrolyte the contact of ions with metal interface increases.
