Quick Summary

A weak electrolyte is a substance that dissociates only to a small extent into ions when dissolved in an ionizing solvent. Unlike strong electrolytes, such as ordinary salt or hydrogen chloride, which dissociate completely, weak electrolytes like acetic acid in water only partially break down into charged particles. For instance, in an aqueous solution, acetic acid can form hydrogen ions and acetate ions, but less than 1 percent of the acetic acid molecules dissociate. This limited dissociation means that solutions of weak electrolytes exhibit some properties of electrolyte solutions, such as being fair conductors of electricity, but are generally classified closer to nonelectrolyte solutions.12

Weak electrolytes
While classification under the heading electrolyte-solution or nonelectrolyte-solution is often useful, some solutions have properties near the boundary between these two broad classes. Although such substances as ordinary salt and hydrogen chloride are strong electrolytes—i.e., they dissociate completely in an ionizing solvent—there are…
