Question

a solution is made by completely dissolving 90. grams of kno3 in 100 grams of water in a beaker. the temperature of this solution is 65 degrees celsius.describe the effect on the solubility of a gaseous solute in this solution when the pressure on the solution increases

Answer 1

Pressure has no effect on the solubility of KNO3 in water. This is because it is solid in liquid type of solution. In solid in liquid type of solution, solid is solute (minor component), liquid is solvent (major component). For solid in liquid type of solutions, solubility is independent of pressure. 

On other hand, pressure has a pronounced effect on the solubility of gas in liquid type solutions. In such system, gas is solute (minor component) and liquid is solvent (major component). Example of such solution is aerated water. Herein, CO2 is dissolved in water. In such gas in liquid type of solutions, solubility increases with increasing pressure.
