When you mix sugar into water, it dissolves easily. But if you keep adding more and more sugar, eventually it stops dissolving and settles at the bottom. This is the concept of a Saturated Solution, taught in Class 9 Chemistry (Is Matter Around Us Pure).
The amount of solute present in a saturated solution at a specific temperature is called its Solubility. For example, the solubility of salt (NaCl) in water at 20°C is about 36 grams per 100 mL of water.
A Saturated Solution is a solution in which no more solute can be dissolved in the solvent at a given temperature.
At this stage, the solution has reached its maximum capacity. The point at which it cannot dissolve any more solute is called the Saturation Point.
The saturation point is highly dependent on temperature.
If you cool down a saturated solution, its capacity to hold the solute decreases. As a result, the excess dissolved solute will start to turn back into solid crystals and settle at the bottom.
What Does Potassium Permanganate Oxidize Ethanol To?

Composition of Pure Water — Formula, Elements and Mass Percentage
Pure water (H₂O) is composed of hydrogen (11.11%) and oxygen (88.89%) by mass, in a 2:1 atom ratio. Learn the composition, formula and verification with FAQs.
Reactivity Gradation in Halogens — Order and Reasons Explained
Halogens reactivity decreases from F to I: F > Cl > Br > I. Learn why reactivity decreases down Group 17 with displacement reactions and electron affinity data.
What Happens When Barium Sulphate Is Reduced by Carbon?
Barium sulphate (BaSO₄) is reduced by carbon (coke) at high temperature: BaSO₄ + 4C → BaS + 4CO. This produces barium sulphide (BaS) and carbon monoxide.
