Aqueous solution of ferric chloride is

Assuming that the degree of hydrolysis is small,the $pH$ of $0.1 \ M$ solution of sodium acetate $(K_a = 1.0 \times 10^{-5})$ will be

Identify the weak acid-weak base salt from the following.

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:

The aqueous solution of sodium acetate is:

If the base ionization constant $(K_b)$ of hydrazine $(N_2H_4)$ is $9.6 \times 10^{-9}$,what is the percentage of hydrolysis of a $0.1 \ M$ solution of the salt $N_2H_5Cl$?
