Calculate the hydrolysis constant $(K_h)$ for a salt containing $NO_2^-$. Given that the dissociation constant $(K_a)$ for $HNO_2$ is $4.5 \times 10^{-4}$ and the ionic product of water $(K_w)$ is $1.0 \times 10^{-14}$.

Which among the following is $NOT$ an example of a salt of a strong acid and a weak base?

Which of the following has the highest degree of hydrolysis?

Ammonium acetate which is $0.01 \ M$,is hydrolysed to $0.001 \ M$ concentration. Calculate the change in $pH$ in $0.001 \ M$ solution,if initially $pH = pK_a$.
