When ammonium acetate is heated
Ammonium acetate is also a chemical substance. When it is heated, the reaction occurs, which can be investigated.

When it is heated, ammonium acetate ($CH_3COONH_4 $) gradually changes. When it is heated, according to chemical reasons, the structure of the molecule is easier. Ammonium acetate is decomposed by heat, and one of its changes is to form ammonia ($NH_3 $) and acetic acid ($CH_3COOH $). The reaction formula is roughly as follows: $CH_3COONH_4\ stackrel {\ Delta }{=\!=\!=} NH_3 ↑ + CH_3COOH $.

Looking at this reaction, ammonia gas is colorless and irritating, and it is active and can often be smelled between experiments. Acetic acid also has a unique acid gas, both of which escape from ammonium acetate due to heating. And the progress of this reaction is related to the temperature and environment of the heating. If the temperature is suitable, the reaction can occur smoothly, and ammonium acetate gradually decomposes into ammonia and acetic acid.

However, acetic acid is unstable, and when heated, it may change. If the temperature is higher, acetic acid may further decompose and other products will be produced.

In short, the reaction of ammonium acetate heating is complex and interesting, and it cannot be ignored in the study of chemistry.
