The final answer is a physical change
More Information
Though often considered physical due to no change in the electron shells, some argue it's a chemical change as dissociation into ions occurs. Both sides present valid points.
Tips
Common mistakes include assuming all dissolving processes are physical changes, not considering the ionic dissociation aspect of salt in water.
