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

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

The process of dissolving more closely binds the electrons in the solution.
The process of dissolving more closely binds the electrons in the solution.

The process of dissolving closely binds the ions in the solution.

Answer 1

The correct statement that explains why saltwater conducts electricity well is:

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

When salt (sodium chloride) dissolves in water, it dissociates into its constituent ions (sodium ions and chloride ions). These charged ions are free to move within the solution, allowing it to conduct electricity effectively. Pure water does not have these free ions, and thus does not conduct electricity well.
