A material made up of two or more different substances which are physically combined.

Mixture

A chemical substance composed of many identical molecules that are composed of atoms from more than one element held together by chemical bonds.

Compound

A compound is a pure substance that contains 2 or more elements chemically combined together while a mixture are formed when two substances are added together without chemical bonds being formed.

What is the difference between a mixture and a compound?

Air. It is made of 78% nitrogen and 21% oxygen.

What is an example of a mixture

Water. It is made out of three atoms, two hydrogen and one oxygen.

What is an example of a compound

The quality of being soluble and easily dissolved in liquid

Solubility

It is a special type of homogeneous mixture composed of two or more substances.

Solution

It is a substance, usually a solid, that is dissolved in a solution, which is usually a liquid.

Solute

It is a liquid that dissolves a solid, liquid or gaseous solute.

Solvent

It is basically two substances that are evenly mixed together. One of them is called the solute and the other is the solvent. A solute is the substance to be dissolved (sugar). The solvent is the one doing the dissolving (water).

An example of a solution

The act of changing a fluid by passing it through a filter

Filtration

It is a laboratory technique for the separation of a mixture. The mixture is dissolved in a fluid called the mobile phase, which carries it through a structure holding another material called the stationary phase. The various constituents of the mixture travel at different speeds, causing them to separate.

Chromatography

The action of purifying a liquid by a process of heating and cooling.

Distillation

It is the process by which a solid forms, where the atoms or molecules are highly organised into a structure known as a crystal. Some of the ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas.
