Question
Comment on dilute solution and concentrated solution. Which of them gives the solubility of the solute? Explain.
✓

Answer

Dilute and concentrated solutions are relative terms. The solution obtained by dissolving one teaspoonful of salt in 100 mL of water is dilute compared to a solution obtained by dissolving two spoonfuls of salt in 100 mL of water. None of these gives the solubility of the salt. The idea of solubility can be obtained by dissolving the maximum amount of salt in a fixed quantity of a solvent at a given temperature. Solubility changes with temperature. In the case of a solid solution, solubility increases, but in the case of a gaseous solution, the solubility decreases.
