Electricity and Aqueous Sodium Chloride
Name: Cleveland W.
Why does aqueous sodium chloride conduct electricity?
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.
