Henry's law is important in environmental chemistry, where it predicts the distribution of pollutants between water and the atmosphere. The hydrocarbon toluene (C7H8) emitted in wastewater streams, for example, can pass into the air, where it is degraded by processes induced by light from the sun. The Henry's law constant for toluene in water at 25 °C is 347 atm, when the following form of the law is used: Ptoluene = Ktoluene Xtoluene Calculate the partial pressure of toluene vapor in equilibrium with a solution of 1.39 g of toluene per 1220 L of water. How many toluene molecules are present in each cubic centimeter of vapor? Ptoluene atm

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.
