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
When salt is dissolved in water, it dissociates into ions (sodium and chloride ions). These ions are free to move and carry electric charge, allowing the solution to conduct electricity. In pure water, there are no free ions to carry charge, and in pure salt, the ions are not free to move around. So, the presence of ions in the saltwater solution is what allows it to conduct electricity well.
