The solubility of KNO3(s) in water increases as the..
a. Pressure on the solution decreases
b. Temperature of the solution increases
c. pressure on the solution increases
d. Temperature of the solution decreases
The answer would be b. Temperature of the solution increases
Temperature determines the kinetic energy of the water molecule. Higher temperature will cause the molecule to moves faster and the compound (KNO3) could break solute molecule easier make it become more soluble. A higher pressure will increase the solubility of a gas, not solid
