On dilution,the $pH$ of $CH_3COONH_4$ solution:

Which of the following salts contains an anion that undergoes hydrolysis?

When a salt of a weak acid and a weak base is dissolved in water at $25\,^{\circ}C$,the $pH$ of the resulting solution will always :-

The $pH$ of an aqueous solution of $CH_3COONH_4$ is found to be $6.7$ at $25\,^{\circ}C$. The concentration of the $CH_3COONH_4$ solution is ($K_a$ for $CH_3COOH = 1.0 \times 10^{-5}$ and $pK_b$ for $NH_4OH = 4.4$)

When a solution of $NH_4Cl$ is diluted,its $pH$ .....
