    Sodium Chloride - Neutral or Ionic and Why?

    I know that sodium chloride solubilized in water is an electrolyte - meaning it conducts electricity when dissolved in water. I think this means that table salt is an ion, because it carries electrical charge. I get confused because I thought a definition of a salt was an ionic compound that...
