Example 3

easy
Is dissolving sugar in water a chemical reaction? Explain.

Solution

  1. 1
    Dissolving sugar is a physical change — no new substances are formed.
  2. 2
    The sugar molecules remain intact; they simply disperse among water molecules. Evaporating the water recovers the original sugar.

Answer

No, it is a physical change, not a chemical reaction.\text{No, it is a physical change, not a chemical reaction.}
Chemical reactions produce new substances with different properties. Dissolving is reversible and does not change the chemical identity of the solute.
