Solute The substance that dissolves.

Dissolving This is when a solid (e.g. salt) is added to water and the solid particles fill the spaces between the water particles; they mix with the water.
Mixture This is when two or more substances are mixed up but not chemically joined. They can easily be separated.
Suspension A suspension is a mixture that is opaque. It can be coloured.
Filtration This is where you filter a suspension through a filter, leaving the residue (the solute particles) behind in the filter, with the filtrate (the substance being filtered) being separated from it.
Evaporating This is when you heat the water/substance from the solution, to get the solute back.
