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. In chemistry, after studying solutions and properties of the solution, one can understand that a solution can reach a status of saturation. This state is when the solution has reached a point in which no more solute can be added. Addition of solute after this point would result in a solid precipitate or gas being released. Such a mixture is called a saturated solution. A saturated solution is prepared by continuously adding solute to the solution until a stage is reached where the solute appears as a solid precipitate or as crystals to form a highly saturated solution. Types of SaturationThe main three types of saturation are explained below.

Factors affecting the Point of Saturation
Everyday Examples of Saturated Solution
A soda is a saturated solution of carbon dioxide in water. This is why, when the pressure is released, carbon dioxide gas forms bubbles. Adding chocolate powder to milk so that it stops dissolving forms a saturated solution.
Adding a spoonful of sugar to a cup of hot coffee produces an unsaturated sugar solution. Vinegar is an unsaturated solution of acetic acid in water. Mist is an unsaturated (but close to saturated) solution of water vapor in air.
The difference between saturated and unsaturated fat lies in the number of double bonds in the fatty acid chain. Saturated fatty acids lack double bonds between the individual carbon atoms, while in unsaturated fatty acids there is at least one double bond in the fatty acid chain.
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.
An aqueous solution can be rendered supersaturated by first dissolving the solute in water at an elevated temperature using enough to give a concentration just under its solubility at that temperature. After the last of the solute crystals have dissolved the solution is cooled. Join BYJU’S to clarify your doubts by the expert mentors.

If the temperature of a saturated solution is increased or it is heated a bit then a little more amount of solute could be added and dissloved into the solution and then the solution would become super saturated.
if the saturated solution is heated then the kinetic energy of the particles increases and there is some more space for the solute to be dissolved and so we can say that an unsaturated solution is obtained and if a saturated solution is cooled then the kinetic energy is decreased and thus the inter particle space is decreased and thus the particles become visible and crystallisation takes place hope it helped :)
if a saturated solution is heated then the solute settles in the bottom forming crystals
A saturated solution is a solution in which no more of a solute can be dissolved in a solvent.So to dissolve more of the solute we can heat the solution.Thus the increase in temperature(heat) causes more of the solute to dissolve in the molecules of the solvent.
First of all you need to know that there are two types of nature of salts solubility. If heat energy is absorbed or needed in the process of dissolving salt then it is known as Endothermic in Nature. In this Nature, the solubility increases with rise temperature. If heat energy is evolved or released in the process of dissolving of salts then it is known as Exothermic in Nature. In this nature, solubility decreases with rise in temperature. Examples of Salts that are Endotheremic in nature. - NaCl ( Sodium chloride ) , KCl ( Pottasium Chloride ) , NaNO2 ( Sodium Nitrate ) , NH4Cl ( Ammonium Chloride ) etc. Examples of Salts that are Exotheremic in nature - Lithium Carbonate ( Li2CO3 ) , Na2CO3 ( Sodium Carbonate monohydrate ) , Cerium Sulfate [ Ce(SO4)2 ] etc.Now to your question, If the salt is if endotheremic nature then the solubility will rise on increase in temperature , for ex if the solubility of NaCl is 54 at 36 degree celcius, then if there is rise in the temp. the solubility may become 56 or 58 or [ 54 + x ]. And if the salt is of exotheremic nature than it's solubility will decrease if there is any rise in temp, for ex if the solubility of Na2CO3 is 51 at temperature 36 degree celcius, then if there is any rise in the temperature the solubility may becom 50 or 48 or 43 or [ 51 - x ].
the effect of heat on saturated olution is the solution would be super saturated as a result |
