WitrynaImpure substances are also called mixtures. Mixtures are further divided into homogenous or heterogeneous mixture. A homogeneous mixture occasionally called a solution, is comparatively unvarying in configuration or constant. Every unit of the mixture is like every other unit. WitrynaThe properties of pure substances in GCSE Chemistry include their melting point, boiling point, density, conductivity, and solubility. These properties can be used to identify a pure substance and to distinguish it from other substances. →What are formulations in GCSE Chemistry?
