Problem: A KNO3 solution containing 51 g of KNO3 per 100.0 g of water is cooled from 40˚C to 0˚C. What will happen during cooling?

FREE Expert Solution

solubility at 40°C → 65 g KNO3 in 100 g H2O

solubility at 0°C → 15 g KNO3 in 100 g H2O


40°C → 0°C 

decrease in solubility

less solute will be soluble in solvent
