Preparing and Separating Mixtures

When solid substances are mechanically mixed together

Solid-Solid mixture

Is the application of heat to a solid

Melting

Changes to a liquid above a temperature

Melting point

Solutions where water is used as a solvent

Aqueous solutions

Refers to the amount of solute dissolved in a certain amount of solvent

Concentration

Is the addition of water, or other solvents, to reduce the concentration of a solution

Dilution

Increases the speed at which a solute dissolves in a solvent

Stirring

Involves raising the temperature of the solvent to be able to extract the components of the solute

Heating

Or reducing the particle size of a solid solute,will also help increase the rate of dissolving of solids in liquids

Crushing

Three different types of mixtures based on their components

Solid-solid mixtures

liquid-liquid mixture

Solid-liquid mixtures

Types of Homogeneous

Solvent

Solute

Types of Heterogeneous

Suspension

Colloid
