A saturated solution is one in which no more solute can dissolve in the solvent at a given temperature.

Solubility refers to how well a solute is able to dissolve in a solvent to create a solution.

A line that depicts the trend of scattered data plots on a graph.

Saturated solutions

Science

In the Separation Techniques unit, pupils will build on their knowledge of solutions to learn about methods for separating mixtures, including filtration, evaporation, distillation, and chromatography.

In the Solid, Liquid and Gas States and Changes of State unit, pupils learned to categorise substances into the solid, liquid or gas state and explored particle behaviour during changes of state.
