matter impure pure at least two substances one substance mixture homogeneous heterogeneous two phases oil/water milk one phase Tab water solution
Phase region of physical uniformity all parts of that space have the same physical properties color, density, conductivity, magnetism, …
mixture homogeneous heterogeneous two phases oil/water milk one phase Tab water solution Solute(s) solvent • Less abundant or other component(s) of mixture • salts in tab water • more abundant • component of mixture • water in tab water • nitrogen in air Water always solvent even in 98% H2SO4
