Statement I : When aqueous solution of CH₃COONH₄ is diluted, then its degree of hydrolysis increase.

Statement II : Ammonium acetate is the salt of weak acid and weak base, its degree of hydrolysis depend on the concentration.

CH₃COONH₄ is a slat of weak acid and weak base. Such a salt solution has a P^H given by

${\mathrm{P}}^{\mathrm{H}}=\frac{1}{2}\left[{\mathrm{P}}^{{\mathrm{K}}_{\mathrm{w}}}+{\mathrm{P}}^{{\mathrm{K}}_{\mathrm{a}}}-{\mathrm{P}}^{{\mathrm{K}}_{\mathrm{b}}}\right]$

Which is independent of concentration.

Also, degree of hydrolysis of such a salt solution is given by $\frac{\mathrm{\alpha }}{1-\mathrm{\alpha }}=\sqrt{\frac{{\mathrm{K}}_{\mathrm{w}}}{{\mathrm{K}}_{\mathrm{a}}{\mathrm{K}}_{\mathrm{b}}}}$

Therefore, α is independent of concentration
