Question

Which of the following is/are the applications of Pourbaix diagrams?

(a) Predicting the spontaneous direction of reactions

(b) To reduce corrosion attack

(c) To reduce corrosion attack, to predict the direction of spontaneous reaction and to estimate the composition of corrosion product

(d) To estimate the composition of corrosion product

This question was addressed to me in an interview for internship.

This is a very interesting question from Modern Theory Principles topic in chapter Modern Theory Principles of Corrosion Engineering

Answer 1

Correct choice is (c) To reduce corrosion attack, to predict the direction of spontaneous reaction and to estimate the composition of corrosion product

To explain I would say: Applications of Pourbaix diagrams:

i. Predicting the spontaneous direction of reactions

ii. To reduce corrosion attack

iii. To estimate the composition of corrosion product.
