On the valence of potassium acetate
Potassium acetate, the analysis of its valence is related to the basis of chemistry. Potassium, among the elements, often shows + 1 valence. Because of its atomic structure, the outer layer has only one electron, which is easy to discard to reach a stable state, so it shows + 1 valence.

Acetate, the whole shows -1 valence. The structure of acetate, the atoms of carbon, hydrogen, and oxygen are connected by covalent bonds, and the electron distribution makes the entire atomic group negatively charged.

In potassium acetate ($CH_3COOK $), potassium ions ($K ^ + $) and acetate ions ($CH_3COO ^ - $) are ionic bonded. According to the rule that the valence algebra sum is zero, potassium + 1 valence and acetate-1 valence are mutually beneficial, making potassium acetate electrically neutral.

Therefore, it can be seen that the valence of potassium in potassium acetate is + 1, and the valence of acetate is -1. The two complement each other to form the stable structure of this compound, which is of great significance for chemical reactions and the exploration of material properties.
