how to test the purity of water chemically

Best answer

The purity of water can be tested byevaporating it (to dryness) on an evaporating dish or by measuring its boiling point. If dissolved salts are present,then evaporating the water will leave them behind. The purer the water,the less solid residue will be left. Pure water will leave no residue.
