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 (sodium chloride, NaCl) dissolves in water, it dissociates into its constituent ions (Na⁺ and Cl⁻). These ions are charged particles that can move freely through the solution, allowing it to conduct electricity effectively.
**The salt dissolving frees the electrons in the solution, allowing them to move freely.**
