Sulfuric acid is a strong electrolyte because it completely dissociates into its ions when dissolved in water. This means that all of the sulfuric acid molecules break apart into hydrogen ions (H+) and sulfate ions (SO42-). As a result, sulfuric acid is able to conduct electricity very well.

Acetic acid, formic acid, and citric acid are all weak electrolytes. This means that they only partially dissociate into their ions when dissolved in water. As a result, these acids do not conduct electricity as well as sulfuric acid.
