It means that magnesium hydroxide can no longer be dissolved at this temperature


Saturated solution


Saturated solution means that the solute cannot be dissolved in a certain amount of solvent at a certain temperature, which means that the concentration of the solution remains unchanged. From the above expression, the saturated solution must be at a specific temperature and a certain dose for the same substance.


Unsaturated solution,


A solution in which a substance can be dissolved again in a certain amount of solvent at a certain temperature is called an unsaturated solution of this solute.


How to turn a saturated solution into an unsaturated solution (most solvents can do this)
