CO2 in water has a Henry’s law constant KB = 1.25 × 106 torr. How many liters of CO2 are needed to make 1 liter of sparkling water at 1 atm and 300 K? The density of water is 1 kg/L and it does not change as CO2 is dissolved. N.B. Treat gas as a solute, and note that in order for water to “sparkle” the partial pressure of CO2 in the vapor phase must equal the atmospheric pressure (note that this neglects the partial pressure of the water vapor).

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
