What are Mixtures and Solutions ?

• A mixture is a substance mixed with other substances.

• A solution is a mixture of a solvent and solute

• ex of mixtures are: rocks and sand , rice and pins ,

• ex of solutions: water and sugar , lime and water

Solute

Solubility

Solubility is the ability of a solid, liquid, or gaseous chemical substance (referred to as the solute) to dissolve in solvent (usually a liquid) and form a solution

Suspension

When a substance does not dissolve (insoluble) we get a suspension

For example, when you try to mix sand in water
