What is a saturated solution and how can we make a saturated solution?

A saturated solution has dissolved maximum solute at given temperature; we make it by adding solute until no more dissolves.

• At a given temperature, a solvent can dissolve only a limited amount of solute. When that limit is reached, the solution is saturated.
• To make it: gradually add solute while stirring until extra solute no longer dissolves (some remains undissolved). That point is saturation.
• Temperature matters: at higher temperature, many solutes dissolve more, thus saturation point changes with temperature.
