Concept explainers
Interpretation:
The original solution has to be identified if addition of a small crystal of
Concept Introduction:
Solution:
It is the homogeneous mixture of two or more substances.
In such a mixture, solute is a substance (of lower proportion) dissolved in another substance (of larger proportion), called solvent. In aqueous solution, the solvent is water.
Generally solution are classified into three types as follows,
- Saturated solution
- Unsaturated solution
- Supersaturated solution
Saturated solution is the solution that contains maximum quantity of solute dissolved in the solvent. In the given volume of saturated solution amount of solute dissolved in the solvent called solubility.
Unsaturated solution is the solution that contains less quantity of solute than saturated solution.
Supersaturated solution contains more solute than solute present in the saturated solution.
