An aqueous solution of potassium formate is ...........

The aqueous solution of $AlCl_3$ is:

The hydrolysis constant of $0.01 \ M$ methylamine hydrochloride is....... [ Given: $K_b = 5 \times 10^{-4} $ ]

Hydrolysis of sodium acetate will give:

In the equilibrium $A^{-} + H_{2}O \rightleftharpoons HA + OH^{-}$ $(K_{a} = 1.0 \times 10^{-5})$,the degree of hydrolysis of a $0.001 \ M$ solution of the salt is:

Calculate the $pH$ at the equivalence point in the titration of $25 \ mL$ of $0.1 \ M$ formic acid with a $0.1 \ M$ $NaOH$ solution (given that $pK_a$ of formic acid $= 3.74$). $[log \ 2 = 0.30]$
