An aqueous solution that can conduct an electric current is called conductive. The unit of electrolytic conductivity is siemens per meter (S/m). Conductive solutions are, for example, salts (ionic compounds) dissolved in water or someacids.

Water itself is not electrically conductive. However, when anionic compound is dissolved in water, it dissociates intocationsandanionsenabling a flow of electric charges through the solution.
