Electrolytic conductivity

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 some acids.

Water itself is not electrically conductive. However, when an ionic compound is dissolved in water, it dissociates into cations, cat-ions and anions an - i - ons enabling a flow of electric charges through the solution.
