Question

Define saturated unsaturated and supersaturated solution

Answer 1

SATURATED SOLUTION : The term saturated solution is used in chemistry to define a solution in which no more solute can be dissolved in the solvent. It is understood that saturation of the solution has been achieved when any additional substance that is added results in a solid precipitate or is let off as a gas. In other words, a saturated solution is a solution that contains the maximum amount of solute that can be dissolved under the condition at which the solution exists.

UNSATURATED SOLUTION : Unsaturated solutions are those solutions which contain less amount of solute in them than that of the actual amount of solvent which can be dissolved. In an unsaturated solution, the concentration of solute is much lower than its solubility equilibrium. Each solute will have a limit with respect to the specific solvent.

SUPERSATURATED SOLUTION : A supersaturated solution contains more dissolved solute than required for preparing a saturated solution and can be prepared by heating a saturated solution, adding more solute, and then cooling it gently. Excess dissolved solute crystallizes by seeding supersaturated solution with a few crystals of the solute.

Answer 2

Answer:

A solution is a specific kind of homogenous mixture made up of two or more components that is used in chemistry. A solute is a substance that has been dissolved in a solvent, which is the other substance in the mixture.

Explanation:

1.Saturated solution=In chemistry, a solution in which no more solute can be dissolved in the solvent is referred to as a saturated solution. When any extra ingredient added results in a solid precipitate or is released as a gas, it is believed that saturation of the solution has been accomplished. In other terms, a saturated solution is one that has the most solute that can dissolve under it given the circumstances in which it exists.

2.Unsaturated solutions=Unsaturated solutions are ones that have a lower solute concentration than the maximum amount of solvent that can dissolve them. The concentration of the solute is substantially lower than its solubility equilibrium in an unsaturated solution. There will be a limit for each solute in relation to the particular solvent.

3.Supersaturated solution=By heating a saturated solution, adding additional solute, and then gradually cooling it, one can create a supersaturated solution, which has more dissolved solute than needed to create a saturated solution. By introducing a small number of the solute crystals into the supersaturated solution, extra dissolved solute crystallises.
