On the Analysis of the Acidity and Basicity of Ammonium Acetate
The taste of substances is related to its composition and structure. Ammonium acetate is a common salt in chemistry. To determine whether its solution is acid, alkali or neutral, the reason for its hydrolysis should be studied.

Ammonium acetate is composed of ammonium ion ($NH_ {4 }^{+}$） and acetate ion ($CH_ {3} COO ^ {-} $). Ammonium ions can be hydrolyzed in water. The reaction formula is $NH_ {4} ^ {+} + H_ {2} O\ rightleftharpoons NH_ {3}\ cdot H_ {2} O + H ^ {+} $. This process increases the concentration of hydrogen ions in the solution, which tends to make the solution acidic.

And acetate ions can also be hydrolyzed, and the reaction is $CH_ {3} COO ^ {-} + H_ {2} O\ rightleftharpoons CH_ {3} COOH + OH ^ {-} $, which increases the concentration of hydroxide ions in the solution and tends to make the solution alkaline.

As for the final acidity and alkalinity of ammonium acetate solution, it really depends on the comparison of the degree of hydrolysis between the two. The acidity of acetic acid and the alkalinity of ammonia monohydrate are similar in strength. Therefore, the degree of hydrolysis of ammonium ion and acetate ion is equivalent, and the concentration of hydrogen ion in the solution is almost equal to the concentration of hydroxide ion.

From this point of view, ammonium acetate solution is almost neutral. The properties of covering substances cannot be understood overnight, and it is necessary to study their microscopic changes in order to understand their essence. This is especially important in the field of chemistry.
