Question:
Why does aqueous sodium chloride conduct electricity?


Replies:
Cleveland,

Pure water is a rather poor conductor of electricity because, for the most part, it exists as electrically neutral molecules -- that is, the molecules carry no electric charge. When salt (or any other soluble ionic compound) is dissolved in water, the NaCl dissociates into Na+ and Cl- ions. These positive and negative ions represent the charge carriers in solution. because they are mobile and can accept and transfer electrons through the liquid.
