The stainless steel has to be identified as homogenous or heterogeneous mixture. 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.
