Solutions (= homogeneous mixtures) The two components of a mixture: 1.solute (the substance being dissolved) 2.solvent(the medium that dissolves the solute)

Types of Mixtures 4.2 Notes

Solutions Homogeneous 2 or more substances in a single phase (solids, liquid, or gas) Particles are small, do not block light in liquids, cannot be filtered Consists of 2 parts Solute – substance dissolved Solvent – substance doing the dissolving

Suspensions Heterogeneous Particles are large, block light, settle out Particles are more or less evenly dispersed through liquid or gas Particles can be filtered out

colloids Homogeneous Particles are intermediate in size, between solution & suspension, cannot be filtered Tyndall Effect - Particles block & scatter light Brownian Motion – Particles are in random motion which causes tyndall effect
