Question

Explain what would happen if a saturated solution of kno3 at 50°c is heated

Answer 1

It depends upon exactly what you mean by saturated. If it is just saturated and there is no solid in the solution, nothing will happen. If, however, there is a relatively small amount of KNO3 solid, the solid will dissolve as the solution is heated and the solution will be either saturated or unsaturated depending upon how high the new temperature is. If there is a relatively large amount of excess solid KNO3, then more KNO3 will dissolve but it could still be saturated.
