Contaminants in the tap water may alter the color of the flame produced. This basically means that not only would the desired sample be burned, but also would any contaminants in the tap water. Therefore, to ensure the color of the flame produced is only that of the tested substance, distilled water alone must be used.

Why are flame tests useful when making fireworks?
hi, the metal salts used in the flame tests are the same as those used to make fireworks. when the metal salt is heated the electrons get excited and jump to a higher level. As they get less excited they drop back down a level and the energy they lose is lost as light. This is what we see as the colour.
