Salt Water Can Support An Electrical Current The chemical make-up of sodium chloride is NaCl. Sodium Chloride is composed of is composed of a negatively charged chloride ion (Cl) and a positively charged sodium ion (Na). So I believe that when sodium chloride is dissolved in water the two ions that compose the sodium chloride should separate, and support an electrical current that would be supplied by a nine-volt battery Solutions are evenly distributed mixtures of at least two substances, but they are not limited to just two substances. The most abundant substance in a solution is ca
