On the reaction equilibrium formula of barium hydroxide and acetic acid
There is a reaction of barium hydroxide ($Ba (OH) _2 $) and acetic acid ($CH_3COOH $). In the case of acetic acid, weak acid is partially ionized in water, while barium hydroxide is a strong base and completely ionized.

When the two meet, the hydroxide ion of barium hydroxide ($OH ^ - $) combines with the hydrogen ion of acetic acid ($H ^ + $) to form water ($H_2O $). In the initial stage of the ion reaction, acetic acid continuously ionizes hydrogen ions to respond.

Write its chemical equation as: $Ba (OH) _2 + 2CH_3COOH = Ba (CH_3COO) _2 + 2H_2O $. Looking at this formula, the number of atoms of each element on the left and right sides is equal, which conforms to the law of conservation of mass. This is the equilibrium equation for the reaction of barium hydroxide and acetic acid.

covers chemical reactions, all follow certain laws. The book of equilibrium formulas is the key to clarifying the essence of the reaction and exploring the reaction process. In this reaction, starting from the properties of the substance, the equilibrium formula can be deduced, which can lay the foundation for subsequent studies, such as the calculation of reaction heat and the discussion of reaction rate.
