The correct explanation for why salt water becomes a good conductor when salt is dissolved in water is:
**The salt dissolving frees the electrons in the solution, allowing them to move freely.**
When salt (NaCl) dissolves in water, it dissociates into sodium (Na⁺) and chloride (Cl⁻) ions, which are charged particles. These ions are able to move freely in the solution, allowing for the conduction of electricity.
**The salt dissolving frees the electrons in the solution, allowing them to move freely.**
