"The Formula of Ammonium Acetate"

The principle of chemistry, subtle Austrian. To understand the formula of ammonium acetate, we should study the wonder of its elemental combination. Ammonium acetate is formed by the combination of ammonium ion and acetate ion.

Ammonium ion, its symbol is $NH_ {4 }^{+}$， is positive monovalent. Acetate ion, symbol is $CH_ {3} COO ^ {-} $, is negative monovalent. When the two meet, according to the balance of charge, positive and negative attract, combine in a ratio of one to one, and then form ammonium acetate.

Therefore, the chemical formula of ammonium acetate is $CH_ {3} COONH_ {4} $. This formula is also simple and clear, showing the rules of chemistry, allowing scholars to know the essence of its composition and serving as the foundation for studying all things in chemistry.
