Final answer:
HC2H3O2, which is acetic acid, is a weak acid that does not dissociate completely in solution, unlike non-electrolytes that do not ionize at all. This is represented by a reversible reaction in a chemical equation. Non-electrolytes, in contrast, are substances that remain intact in solution.
Step-by-step explanation:
The formula HC2H3O2 refers to acetic acid, which is a weak acid. Weak acids do not dissociate completely in water, meaning they do not release all of their hydrogen ions into the solution. Instead, the dissociation is a reversible reaction. The formula for the dissociation of acetic acid in water is as follows:
HC2H3O2 (aq) \(ightleftharpoons\) H+ (aq) + C2H3O2- (aq)
Acetic acid is not one of the few strong acids that dissociate completely, as indicated by the lack of its presence on lists of strong acids. This reversible behavior is characteristic of weak acids and contrasts with the behavior of non-electrolytes, which do not ionize in solution at all. Examples of non-electrolytes include substances like wood, CCl4 (carbon tetrachloride), and C12H22O11 (sucrose).
