Question

Pure water and pure salt are poor conductors of electricity when salt is dissolved in water, the resulting solution conducts, electricity, well. Which statement explains why this occurs with these substances?

Answer 1

When salt is dissolved in water, it dissociates into positive sodium ions (Na+) and negative chloride ions (Cl-). These ions are free to move and carry electric charge within the solution. This is why the resulting solution conducts electricity well.
