Water is a mixture or pure substance has to be identified and explained. Concept introduction: Mixture: A mixture always contains two or more substances that can be present in varying amounts. The components of a mixture do not lose their identities and may be separated by physical means. There are two types of mixture, Homogeneous mixture Heterogeneous mixture Homogeneous mixture: Homogenous mixture consist of a single phase be it liquid, gas, or solid the chemical composition is the same for any sample of the mixture. Heterogeneous mixture: Heterogeneous mixture consist of different phase are not uniform they will not have an identical composition Pure substance: A pure substance (element or compound) always has a definite composition by mass. The elements in the compounds lose their identities and may be separated only by chemical means.
