A saturated sample containing the max number of solute that can dissolve, while an unsaturated concentration reaches less than the maximum amount of solute that can dissolve.

Given:

A spoonful of salt added to boiling water dissolves.

A tablespoon of salt solvated in boiling water The above makes reference to an unsaturated solution so because liquid in an unsaturated solution disperses more solute till the solution has become saturated, as well as the solubility of a solid solute increases with the increasing solution temperature.

Given:

A layer of sugar forms on the bottom of a glass of tea as ice is added.

As ice is got to add to something like a glass of tea, a surface of sugar forms just on bottom. Because the dissolution rate of a solid solute declines with temperature, this relates to a saturated solution.

As a direct consequence, once ice is added, the solubility of sugar in chai decreases, as well as excess sugar settles to the bottom of the glass as a layer.

Given:

A kidney stone of calcium phosphate forms in the kidneys when urine becomes concentrated.

A calcium phosphate kidney stone forms within the kidneys when urine becomes concentrated. Whereas an excess of calcium and phosphate in urinary causes stones, this refers to a saturated solution.
