Objectives
1. Distinguish between hetergeneous and homogeneous mixtures.
2. List different solute-solvent combinations.
3. Compare the properties of solutions, suspensions, and colloids.
Solutions• Solution –
homogeneous mixture of two or more substances in a single phase; even distribution of particles
• Soluble – able to be dissolved .
Types of SolutionsSolute Solvent Example
Gas Gas Air
Gas Liquid Soda
Gas Solid Methane hydrates
Liquid Gas
Liquid Liquid Vinegar
Liquid Solid Dental fillings
Solid Gas
Solid Liquid Saltwater
Solid solid alloys
Suspensions and ColloidsSuspension – mixture with large (> 1000 nm) solute
particle sizes; particles settle out over time.
Examples: paint, muddy water
Colloid – mixture with intermediate solute particle sizes (between 1 -1000 nm); particles remain dispersed over time
Examples: aerosols, foam, mayonaisse
