Question

how will you prepare a saturated solution of potassium nitrate at 45 degree Celsius what happen when the solution is cooled to 25 degree Celsius

Answer 1

A saturated solution is a solution that contains the maximum amount of solute dissolved into a solvent. A supersaturated solution is where more than the maximum solute is in a solvent, so that some solute is not dissolved.

Answer 2

With only 100 g of glucose dissolved, the solution is now unsaturated. If we next cool the mixture back to 25 °C, 9 g of glucose should precipitate from solution. If glucose crystals do not form, the system has more dissolved glucose (100 g) than it can hold at 25 °C (91 g). We have a supersaturated solution.
