Question

This section contains questions each with two columns-I and II. Match the (salt solution) given in column I with that pH in column II.

Answer 1

(A) The pH of the salt solution 0.1 M KCN is $6.5+\frac{1}{2}p{K}_a$.
(B) The pH of the salt solution $0.1MPh\stackrel{\oplus }{N}{H}_3]C{l}^{⊝}$ is $7.5-\frac{1}{2}p{K}_b$.
(C) The pH of the salt solution 0.1 M KCl is 1.
(D) The pH of the salt solution $0.1MC{H}_{3}COON{H}_4(K_a=K_b)$ is 1. It is calculated by the expression $7.5+\frac{1}{2}p{K}_a-\frac{1}{2}p{K}_b$.
