The reaction of ammonium acetate in water

The change of the male substance in water is a small matter. The reaction of ammonium acetate in water should be analyzed in detail.

Ammonium acetate, its molecular formula is $CH_3COONH_4 $. When placed in water, the water is well soluble, and ammonium acetate can be dissociated. Ammonium acetate enters water, and the following dissociation occurs: $CH_3COONH_4\ longrightarrow CH_3COO ^ - + NH_4 ^ + $.

However, water is not static, and water has its own weak dissociation, which is $H_2O\ rightleftharons poH ^ ++ OH ^ - $. The $CH_3COO ^ - $of ammonium acetate dissociation can combine with the $H ^ + $of water dissociation to produce $CH_3COOH $of acetic acid; and $NH_4 ^ + $combines with $OH ^ - $to produce ammonia monohydrate $NH_3\ cdot H_2O $. The reaction of the two is as follows: $CH_3COO ^ - + H ^ +\ rightleftharpoons CH_3COOH $, $NH_4 ^ ++ OH ^ -\ rightleftharpoons NH_3\ cdot H_2O $.

Due to the existence of the above reaction, the ionization equilibrium of water is shifted. Acetic acid and ammonia monohydrate are both weak electrolytes and partially ionized. The acidity and alkalinity of ammonium acetate in water depends on the degree of ionization between acetic acid and ammonia monohydrate. The ionization constants of the two are similar, so the aqueous solution of ammonium acetate is almost neutral.

Looking at the reaction of ammonium acetate in water, it can be seen that the substance is not simply mixed in water, but has complex chemical changes, which are related to the principle of ionization and balance. Scholars should study it in depth to understand the beauty of chemical changes.
