What must a solution contain in order to conduct electricity?

According to Boundless, solutions must contain a high amount of ions in order to conduct electricity. Salts, acids or bases, if dissolved in a solvent such as water, release ions and form an electrolyte solution.

Nonelectrolyte solutions are incapable of conducting electricity due to the bonds of the solute being covalent instead of ionic. Electrolytes are classified into two groups: strong or weak. If an electrolyte compound does not entirely dissolve within a solution, it releases only a small amount of ions, thus leading to poor conductivity and rendering it weak. Strong electrolytes, by comparison, release all of their ionic bonds when dissolved.
