6.7 Thermodynamics of Solutions

The following terminologies are used in describing properties of solutions. We shall describe the properties of binary solutions.

Molar concentration: It is measured by number of moles of solute in 1 litre of solution. We shall represent molar concentration by CR

Molal concentration: It is measured by number of moles of solute in 1,000 gm of solvent. We shall represent molal concentration by CL.

Molar fraction: Molar fraction or mole fraction of a particular component in a solution is the ratio of the number of moles of this component to the total number of moles present in the solution. We shall represent this by CF.

Mass fraction: Mass fraction of a particular component in the solution is the ratio of mass of ...
