Supersaturated solution: A solution that contains more than the maximum amount of dissolved solute than a saturated solution under the same conditions and no more solute can be added to the solution until the temperature is raised. if cooled carefully the supersaturated solution will stay liquid unless disturbed or seeded with a seed crystal. Supersaturated solutions are extremely unstable, but often require a triggering event to begin . So, when temperature decreases (i.e., when the saturated solution is cooled), solubility also decreases. All of the solute dissolves in the solvent. A supersaturated solution is a solution with more dissolved solute than the solvent would normally dissolve in its current conditions. Supersaturated solution can be prepared using potassium chloride in water: In 100g of water, add KCl and stir. Watch this with PPT-2-Saturation. The easiest method to create a Supersaturated Solution is achieved by cooling. Suppose, 70 g of Na2S2O3 crystal is dissolved in 100 g hot H2O and the .

Factors Affecting Solubility are-. Rather it is about water solution. Note : A supersaturated solution contains more than the maximum amount of solute that can be dissolved at that temperature. Mixture consists of two or more pure substances. The solid crystals will dissolve into the water in the hydrated crystals forming a supersaturated solution. Numericals 9th Chemistry Chapter 6. Justify the following statements with an explanation. When a solute (often a solid) is added to a solvent (often a liquid), two processes occur simultaneously. Example : A solution of 40g Salt in 100 g water is Super Saturated Solution A minor disturbance of the solution or introduction of a "seed" or tiny crystal of solute will force crystallization of excess solute. Concept: Capacity of Water to Dissolve Substances - Saturated, Unsaturated, and Supersaturated Solutions. When it dissolves completely, add more salt to it and keep stirring. If the prepared solution is cooled, it will be saturated when it intersects the line of saturation. An unsaturated solution is a chemical solution in which the solute concentration is lower than its equilibrium solubility. A minor disturbance of the solution or introduction of a "seed" or tiny crystal of solute will force crystallization of excess solute. A) Both assertion and reason are correct and reason is the correct explanation of assertion.

A heterogeneous mixture containing particles large enough to be seen with naked eye and clearly distinct from surrounding medium is called a suspension. Saturated solution - The solution in which maximum amount of solute is dissolved A solution which contains more amount of solute than that is required to saturate it is known as Supersaturated solution. The property by which the amount of solute dissolves in the saturated solution is known as solubility. Effect of Pressure- It is not affected much by a change in pressure. The saturated solution can also be made unsaturated by adding more solvent to it. Unit 11 Solutions Class Packet - Click Pop-up arrow on the right to download. Become more saturated solution if temperature is increased. Supersaturated Solution: It contains more dissolved solute than required for making a Saturated solution. Solubility of a Solute The amount of solute (in grams), which dissolve in 100 g of water (solvent), at a given temperature, is called solubility of the solute at that temperature. At any particular temperature, a solution that has dissolved as much solute as it is capable of dissolving is said to be a saturated solution. A supersaturated solution is a solution with more dissolved solute than the solvent would normally dissolve in its current conditions. In Chemistry 9 Chapter 6 MCQs Test 1, there are 12 MCQs.
