A solution a liquid mixture in which a solute is uniformly distributed within the major component or the solvent. Solutions can be divided into several types depending on the chemical and physical properties of those solutions. Saturated solutions and supersaturated solutions are two such types. A saturated solution is composed of the maximum amount of solutes that can be dissolved in a solvent at a given temperature. A supersaturated solution is composed of more than the amount of solutes that can be dissolved in a solvent at the same temperature. This is the main difference between saturated and supersaturated solution. Show

What is a Saturated Solution Key Terms: Polarity, Precipitation, Saturated Solution, Saturation, Solubility, Solute, Solvent, Supersaturated Solution What is a Saturated SolutionA saturated solution is a chemical solution containing the maximum concentration of a solute dissolved in the solvent. This means no more solutes can be dissolved in that solution. If more solutes are added to this solution, it leaves the excess solutes at the bottom of the container. Figure 01: Adding sugar to water until it no longer dissolves creates a saturated solution. However, the amount of solute that can be dissolved in a particular solvent depends on several factors as given below.
What is a Supersaturated SolutionA supersaturated solution is a solution that contains more solute than the solvent can dissolve. A solution can be brought to the state of supersaturation by changing the normal conditions of a solution. Then the solution will have more solutes than usual at a given temperature. Usually, when a solution gets saturated, the excess amount of solute is deposited at the bottom of the container. But in supersaturated solutions, there is no deposition or precipitation at the bottom. Figure 2: Supersaturation of sugar in water can be used to make rock candy In the formation of a supersaturated solution, special conditions have to be provided to the solution. Since the solubility of a solute is directly affected by the temperature of the solvent, the temperature dependence solubility can be used as a strategy to make a supersaturated solution. Here, we can first dissolve the maximum amount of solute in the solvent at room temperature. Then, more solutes can be dissolved by increasing the heat of the solvent. If we cool this solution at a rate that is faster than the rate of precipitation of solute, the solution becomes supersaturated. Pressure and volume are other factors that can be changed in order to obtain a supersaturated solution. Difference Between Saturated and Supersaturated SolutionDefinitionSaturated Solution:A saturated solution is a solution is a chemical solution containing the maximum concentration of a solute dissolved in the solvent. Supersaturated Solution: A supersaturated solution is a solution which contains more dissolved solute than could ordinarily dissolve into the solvent. Amount of SoluteSaturated Solution:A saturated solution has the maximum amount of solutes that can be dissolved in the solvent at room temperature. Supersaturated Solution: A supersaturated solution has more than the maximum amount of solutes that can be dissolved in the solvent at room temperature. PreparationSaturated Solution: A saturated solution can be prepared by evaporating a solvent from a solution until the solute begins to crystallize or precipitate. Supersaturated Solution: A supersaturated solution can be prepared by adding the solute in excess at a high temperature and suddenly cooling down at a rate that is faster than the precipitation of the solute. PrecipitationSaturated Solution:A saturated solution does not show precipitation at the bottom of the container. Supersaturated Solution:A supersaturated solution shows precipitation at the bottom of the container if the physical conditions are changed. ConclusionA solution is a mixture of a solute and a solvent. In most solutions we know, the solute is the minor component and solvent is the major component. But a saturated solution has the maximum amount of solutes that can be dissolved at a given temperature. We can make a supersaturated solution out of a saturated solution. Then, the amount of solute present in the supersaturated solution will be higher. The main difference between saturated and supersaturated solution is that, at a given temperature, a saturated solution has a maximum amount of solutes in the solution whereas a supersaturated solution has more than the maximum amount of solutes in the solution.

3.0) via Commons Wikimedia What is difference between saturated and supersaturated solution?The solution obtained by dissolving maximum amount of solute at a given temperature is known as saturated solution. A solution which contains more amount of solute than that is required to saturate it is known as supersaturated solution.
What is the difference between saturated solution and unsaturated solution Class 9?A saturated solution is a solution that contains the maximum amount of solute that is capable of dissolving. An unsaturated solution is a solution that contains less than the maximum amount of solute that is capable of being dissolved.
What is supersaturated solution Class 9 Chemistry?Any solution containing more solute than required to prepare a saturated solution at any fixed temperature is called supersaturated solution. Supersaturated solution is a meta-stable state i.e. it will remain in supersaturated state so long it is left undisturbed.
What is saturated in chemistry class 9?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.
