solute + solvent = ?

Solids dissolve in water to make a solution. These solids are soluble.

Solids that don't dissolve are insoluble.

The total mass of a solution equals the mass of solvent added to the mass of the solute.

If you keep adding solutes to a solvent, eventually the solvent will not dissolve.

This is called a saturated solution.

Filtration- used to separate solid particles which do not dissolve in the liquid they are in

Evaporation- used to separate dissolved substances from a solution e.g. salt water

Destillation (evaporation followed by condensation)- used to separate the liquid from the dissolved solid in a solution or one liquid from a mixture of liquids e.g. ink and water

Chromatography- used to separate individual colours from a mixture of colours e.g. ink
