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 40°C
2)50g of KCl in 100mL of H2O at 70°C
3) 120g of KCl in 100mL of H2O at 60°C


My data is:

Temperature82°C 58°C 39°C 18°C 16°C
Solubility(g/100mL)50 42.86 37.5 33.3 30

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