    Mixtures are constituted by more than one kind of pure form of matter, known as a pure substance. Sodium chloride solution is regarded as a mixture since dissolved sodium chloride can be separated from water by the physical process of evaporation.

    A pure substance cannot be separated into other kinds of matter by any physical process. Sodium chloride is a pure substance; it cannot be separated into its chemical constituents - sodium and chlorine - by a physical process.

    Mixtures are formed by combination of two or more pure substance.In sodium chloride solution sodium chloride which is pure substance is added in water which is also a pure substance.So sodium chloride solution is a mixture. While sodium chloride is compound because the in the compound two or more elements combined in proper ratio to form new substance. In sodium chloride the sodium is combined with chlorine. So its an compound which is pure substance
