Which of the following mixtures of KCl in water is a saturated solution and which is an unsaturated solution;
1)100g of KCl in 100mL of H2O at 40C
2)50g of KCl in 100mL of H2O at 70C
3) 120g of KCl in 100mL of H2O at 60C


My data is:

Temperature82C 58C 39C 18C 16C
Solubility(g/100mL)50 42.86 37.5 33.3 30

At temperature 82C the solubility is 50
At temperature 58C the solubility is 42.86
At temperature 39C the solubility is 37.5
At temperature 18C the solubility is 33.3
At temperature 16C the solubility is 30
