MHT CET 2024 Chemistry question

Which of the following cannot be used as standard solution for determination of cell constant of conductivity cell ?

(A)1 M KCl
(B)0·1 M KCl
(C)0·01 M KCl
(D)Saturated KClCorrect

Answer: (D)

Solution

The cell constant is determined by filling the cell with a solution whose conductivity is accurately known and measuring its resistance . Standard KCl solutions of exactly known concentration, namely 1 M, 0.1 M and 0.01 M, have accurately tabulated
