Asubstance is boiled repeatedly and stirred, but the solute never mixes with the solvent. which best describes why?

If the temperature increases, more solute dissolves in the solvent until a point is reached where the solvent can no more dissolve the solute. after we reach this point though we add more and more solute, it doesn't dissolve but settles down in the solution because the solution becomes super saturated.

Abbreviated as mg-25.
