Strong Electrolytes: An electrolyte is a substance that dissociates into its ionic components and these components conduct electricity in aqueous solutions. Strong Electrolyte. A strong electrolyte consists of a solute that dissociates into free ions in large quantity while a weak electrolyte does not release much of the free ions. Those compounds which produce a large number of ions in solution are called strong electrolytes. The general form of the strong electrolyte equation is: strong electrolyte (aq) → cation+ (aq) + anion- (aq).
