The reaction equation of acetic acid and aluminum
acetic acid ($CH_ {3} COOH $) can react with aluminum ($Al $). The chemical equation of the reaction is: $2Al + 6CH_ {3} COOH = 2 (CH_ {3} COO) _ {3} Al + 3H_ {2}\ uparrow $. In this reaction, aluminum, as an active metal, reacts with acetic acid. The aluminum atom loses electrons and becomes aluminum ions ($Al ^ {3 + }$）， hydrogen ions in acetic acid ($H ^{ + }$） get electrons and generate hydrogen gas ($H_ {2} $). Acetate ions ($CH_ {3} COO ^ {-} $) combine with aluminum ions to form aluminum acetate ($ (CH_ {3} COO) _ {3} Al $). From the perspective of the reaction phenomenon, when the aluminum sheet is placed in the acetic acid solution, it is observed that there are bubbles on the surface of the aluminum sheet slowly emerging, which is due to the formation of hydrogen gas. As the reaction proceeds, the aluminum sheet gradually dissolves and the solution forms aluminum acetate. This reaction reflects the reactivity of metallic aluminum and the acidity of acetic acid to a certain extent.
