The of different types of half cells are as follows: (where E is the electromotive force) Which of the above half cells would be preferred to be used as reference electrode?

(A) A
(B) B
(C) C
(D) D

Prashant Kotian · Accepted Answer

Correct answer: C) C. A cell with less variation in EMF with temperature is preferred as reference electrode because it can be used for wider range of temperature without much derivation from standard value. So, according to this option (c) is correct.
