Derivation of the chemical formula of lead (II) acetate
The chemical formula of lead (II) acetate needs to be studied in detail. The properties of lead (II) ions and acetate ions are studied. Lead elements have various valences. In lead (II), lead is + 2 valent, which is the meaning expressed in (II).

Acetic acid is a common organic acid, and its root ion is acetate. Acetate ion, often expressed as\ (CH_ {3} COO ^{-}\) , has a valency of -1.

When the lead (II) ion\ (Pb ^ {2 + }\) combines with the acetate ion, according to the principle that the sum of the valence algebras of each element in the compound is zero. Let the chemical formula of lead (II) acetate be\ (Pb_ {x} (CH_ {3} COO) _ {y}\), then there is\ (+ 2x + (-1) y = 0\). In order to make the equation hold and satisfy the simplest integer ratio, when\ (x = 1\),\ (y = 2\) can be used. The chemical formula for lead (II) acetate is\ (Pb (CH_ {3} COO) _ {2}\).
