On the valence of potassium acetate
Potassium acetate is a common chemical compound. It is composed of potassium ions and acetate ions.

Potassium element is the first main group in the periodic table of elements. The characteristics of this group of elements are that the outer layer has only one electron, and it is easy to lose this electron to achieve a stable electronic structure. Therefore, potassium in compounds often presents + 1 valence.

acetate ion, its chemical formula is\ (CH_3COO ^ -\). The acetate ion as a whole shows -1 valence. The reason is that the atoms in acetate are combined with each other through chemical bonds, and the electron distribution of the whole makes it carry a negative charge of one unit.

From the rule that the valence algebra of the compound is zero, when potassium ion (\ (K ^ +\)) and acetate ion (\ (CH_3COO ^ -\)) combine to form potassium acetate (\ (CH_3COOK\)), the + 1 valence of potassium and the -1 valence of acetate are balanced with each other, so that potassium acetate is electrically neutral.

In summary, the valence of potassium in potassium acetate is + 1 valence, and the valence of acetate is -1 valence. The two match each other to form a stable potassium acetate compound.
