1. Homogeneous MixturesThe composition is uniform throughout.The individual components are not visibly distinguishable.Example: Salt dissolved in water, alloys, vinegar.2. Heterogeneous MixturesThe composition is not uniform throughout.The individual components are visibly distinguishable.Example: Sand and water, salad, oil and water.Mixtures can also be classified based on particle size into three types:Solutions - Particles are very small and evenly distributed (homogeneous).Suspensions - Particles are larger and can settle out over time (heterogeneous).Colloids - Particles are intermediate in size and do not settle out (appear homogeneous but are heterogeneous).
