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

Solutions, Colloids, and Suspensions

Solution Suspension Colloid Salt dissolved in water forms a uniform solution Flour suspended in water has a blue cast from light scattering off the flour particles Milk contains butterfat globules dispersed in a watery liquid

Solution vs. Colloid vs. Suspension All liquid mixtures contain particles. The size of the particles determines whether the liquid is a solution, colloid, or suspension.

Examples of Colloids

Suspensions Largest particles Size of particles causes them to settle out Items that need to be shaken before use

Examples of Suspensions
