The process of dissolving frees the atoms in the solution to move.

Answer 1

The correct response is:

The process of dissolving frees the electrons in the solution to move.

When salt (such as sodium chloride) is dissolved in water, it dissociates into its constituent ions (sodium ions and chloride ions). These ions are charged particles that are free to move in the solution, allowing the solution to conduct electricity well. Pure water does not have these free ions, which is why it does not conduct electricity effectively.
