STATEMENT I: When aqueous, solution of

\mathrm{CH}_3 \mathrm{COONH}_4

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.

View answer and explanation

Correct option: B

Statement I, II are incorrect

Option B (Statement I, II are incorrect) is correct because the degree of hydrolysis for ammonium acetate increases with dilution, and it depends on the ionic product of water, not just concentration.

Given below are two statements: One is labelled as Assertion A and the other labelled as Reason R.
Assertion A: During the boiling of water having temporary hardness,

Mg{(HC{O_3})_2}

is converted to

MgC{O_3}

.
Reason R The solubility product of

Mg{(OH)_2}

is greater than that of

MgC{O_3}

.
