Substances that completely dissociates into ions are called strong electrolytes. Example: Sodium chloride, potassium chloride, lead bromide, sodium hydroxide, potassium hydroxide, hydrochloric acid, nitric acid, sulfuric acid, etc.
- A strong electrolyte is a solute or solution that is an electrolyte that completely dissociates in solution
- The dissociation of a strong electrolyte is apparent by its reaction arrow, which only points toward products. In contrast, the reaction arrow of a weak electrolyte point in both directions. The general form of the strong electrolyte equation is:
strong electrolyte (aq) → cation+ (aq) + anion–
