Question

A solution of CH3COONH4 is neutral? why?​

Answer 1

Ammonium acetate is a salt of weak acid acetic acid and weak base ammonia. ... Hence,the ammonium acetate on hydrolysis gives an equal number of hydrogen ions and hydroxide ions. Hence,the aqueous solution of CH3COONH4 is found to be neutral salt.

Answer 2

AMMONIUM ACETATE -

• Ammonium acetate is a neutral salt that is formed by the reaction of a weak acid and weak base.
• It is formed when acetic acid combines with ammonium hydroxide.
• Acetic acid and ammonium hydroxide have the same dissociation constant of $1.8$ × $10^-^5$.
• When ammonium acetate is hydrolysed in water, it forms ions that react with water to form hydroxide and hydronium ions from acetate and ammonium ion respectively.
• As the dissociation constants are the same, the components will dissociate at the same rate in the water producing the same number of hydronium and hydroxide ions.
• The aqueous solution of ammonium acetate will be neutral as$NH_4^+$ hydrolyses form$H_3O^+$ and$CH_3COO^-$ forms$OH^-$ ions of equal concentration.
