Points to Remember

 

A solution is a homogeneous mixture of two or more substances.

 

An aqueous solution is a solution in which the solvent is water.

 

A non -aqueous solution is a solution in which the solvent is a liquid, other than water

 

A solution in which no more solute can be dissolved in a definite amount of the solvent at a given temperature is called saturated solution.

 

An unsaturated solution is one that contains less solute than the saturated solution at a given temperature.

 

A supersaturated solution is one that contains more solute than the saturated solution at a given temperature.

 

Polar compounds are soluble in polar solvents.

 

Non-polar compounds are soluble in non-polar solvents.

 

In endothermic process, solubility of solid solute increases with increase in temperature.

 

In exothermic process, solubility of solid solute decreases with increase in temperature.
