Assume that 50 g of #KCl# is dissolved in 100 g of water at 100 °C and the solution is allowed to cool to 20°C. How much #KCl# remains in solution? How much #KCl# crystallizes from the solution?
You need to supply data with respect to the solubility of potassium chloride in water at various temperatures.
And even with such data, which would give us the makeup of a saturated potassium chloride solution, supersaturation is certainly a possible outcome.
Here is maybe a useful website.
