Solutions - Concentration terms

For a given solution, the amount of the solute dissolved in a unit volume of solution (or a unit amount of solvent) is termed as the concentration of the solute.

Solutions containing relatively high concentration of solute are called concentrated solutions while solutions of relatively low concentration of solute are termed as dilute solutions.

The concentration of a solution can be expressed in a number of ways.

Solutions - Subjective questions on Solubility of solids in liquids

Subjective Questions 1. Why is benzene soluble in toluene but not in water? Sol. “ Like dissolves like”. Benzene and toluene are non-polar; H 2 O is polar. 2 . Explain, why solute-solute, solvent-solvent and solute-solvent interactions are important in determining the extent to which a solute dissolves in a solvent? Sol : In the dissolution process, solute – solute, solvent – solvent interactio n overcom e and solute – solvent interactions are overcome and solute – solvent i nteractions are established. The solubility of a solute thus, depends on the strength of new solute – solvent interactions relative to the strengths of solute – solute and solvent – solvent interactions. 3. Indicate the type of solute – solvent inter mole...
