Solution

The solution that has relatively a less amount of solute for a given amount of solvent is called dilute solution. The solution that has relatively a large amount of solute for a given amount of solvent is called concentrated solution. The solution, which can dissolve excess solute at the given temperature, is called unsaturated solution at that temperature. This note gives us the information about different types of solution.

Summary

The solution that has relatively a less amount of solute for a given amount of solvent is called dilute solution. The solution that has relatively a large amount of solute for a given amount of solvent is called concentrated solution. The solution, which can dissolve excess solute at the given temperature, is called unsaturated solution at that temperature. This note gives us the information about different types of solution.

Things to Remember

  • The solution that has relatively a less amount of solute for a given amount of solvent is called dilute solution.
  • The solution that has relatively a large amount of solute for a given amount of solvent is called concentrated solution.
  • The solution, which can dissolve excess solute at the given temperature, is called unsaturated solution at that temperature.
  • The solution, which cannot dissolve excess of the solute at a particular temperature, is called a saturated solution at that temperature.
  • The saturated solution at higher temperature that holds excess solute than the required amount for saturated solution at that temperature is called super saturated solution.

Dilute and concentrated solution

The solution that has relatively a less amount of solute for a given amount of solvent is called dilute solution. The solution that has relatively a large amount of solute for a given amount of solvent is called concentrated solution.

Difference between dilute and concentrated solution

Dilute solution Concentrated solution
It contains relatively a less amount of solute for a given amount of solvent. It contains relatively a large amount of solute for a given amount of solvent.
Its density is low. Its density is more.
It has less saturation. It has more saturation.

Saturated, unsaturated and supersaturated solution

The solution, which can dissolve excess solute at the given temperature, is called unsaturated solution at that temperature. It has less density. Precipitation does not appear on cooling.

The solution, which cannot dissolve excess of the solute at a particular temperature, is called a saturated solution at that temperature. On heating, it becomes unsaturated. Precipitation of solute appears on cooling. It has more density.

The saturated solution at a higher temperature that holds excess solute than the required amount for a saturated solution at that temperature is called supersaturated solution.

Difference between saturated and unsaturated solution

Unsaturated solution Saturated solution Supersaturated solution
It can dissolve excess solute at the given temperature. It cannot dissolve excess of the solute at a particular temperature. A supersaturated solution is a solution that contains more solute than would dissolve in a saturated solution at a given temperature.
On heating, it remains unsaturated. On heating, it becomes unsaturated. On heating, it may become saturated
Precipitation does not appear on cooling. Precipitation appears on cooling. Precipitation occurs when the crystal of a supersaturated solution is dropped.
It has less density It has less density than the supersaturated solution but more than the unsaturated solution. It has more density.

Importance of solution

  • Oxygen is found dissolved in water and in air that is used by living organisms for respiration.
  • Plants take minerals and soil from the soil in the form of a solution.
  • Most of the reactions are taking place easily in the form of a solution.
  • Most of the medicines and plants are found in the form of solution,
  • Solution is essential in many industries.
