Whether the tap water leaving white deposits upon evaporation is a mixture or a compound is to be determined. Concept introduction: Mixtures are composed of two or more different compounds or elements or elements and compounds in any ratio/proportion. In a mixture, like air, the individual constituents like oxygen, nitrogen and carbon dioxide retain their individual properties since the different gases in the air are not chemically bonded to each other. Compounds are formed by the combination of two or more different elements in a fixed ratio via a chemical reaction . Compounds are represented by using chemical formulas which contain the alphabetical symbols of the constituent elements along with the number of each element.
