The difficulty in classifying dissolving as simply a physical or a chemical change arises mainly from the fact that some substances keep the same molecular structure when they dissolve, and others do not. When a substance dissolves in a solvent, it may either remain in its molecular form (as in the case of sugar dissolving in water) or dissociate into ions (as in the case of sodium chloride). This variability makes it challenging to categorize the process uniformly as merely physical or chemical.
