Describe how evaporation and crystallisation produce a pure dry salt sample.

Describe how evaporation and crystallisation produce a pure dry salt sample. This objective belongs to Soluble salts within Reactions of acids for AQA GCSE Chemistry 8462. A strong answer should use crystallisation accurately, explain the chemistry behind the statement, and connect the idea back to the exact command in the objective. When revising, separate this point from neighbouring Chemistry ideas by naming the relevant particle, substance, process, calculation, observation, or structure before giving the final conclusion.
