HC2H3O2 is not a strong electrolyte. HC2H3O2 stands for acetic acid, which is a monoprotic acid. Since it is a weak acid, HC2H3O2 is considered a weak electrolyte.
Acetic acid does not disintegrate wholly in water to form anions and cations, which are negatively and positively charged particles. These ions can be utilized for completing an electric circuit, making HC2H3O2 an electrolyte, but a weak one due to the partial ion disintegration in water. Here, HC2H3O2 refers to an aqueous solution, with water as the solvent and HC2H3O2 as the solute. HC2H3O2 is also known by other names, such as ethanoic acid, vinegar acid and ethylic acid.
