Which of the following is not an acidic salt?

If the dissociation constant of $HCN$ is $1.3 \times 10^{-9}$ and $K_w = 1 \times 10^{-14}$,then the $pH$ and percentage of hydrolysis of $\frac{N}{100} \ KCN$ are respectively:

In a solution of sodium acetate,the concentration of $CH_3COOH$ is equal to which of the following?

For a $0.01 \ M$ solution of $NaOCl$,the $K_h$ value is $10^{-6}$. The degree of hydrolysis of the salt is .........$\%$.

Calculate the $pH$ of a $0.1 \ M$ sodium acetate solution. Given: $K_a$ for $CH_3COOH = 1.8 \times 10^{-5}$.

Which of the following salts on dissolution in water gives $pH$ less than $7$ at $298 \ K$?
