When you mix sugar into a glass of water, it dissolves and disappears. But if you keep adding more and more sugar, eventually the water will refuse to dissolve any more. This everyday phenomenon is the perfect example of a 'Saturated Solution', a core concept in Class 9 Chemistry.
The exact maximum amount of a solute (in grams) that can be dissolved in 100 grams of solvent at a specific temperature is called its 'Solubility'.
The beautiful rock candy (Mishri) that you eat is actually made by creating a hot, supersaturated sugar solution and letting it cool down to form giant crystals.
If you cool a saturated solution, its capacity to hold the solute decreases. The dissolved salt or sugar will be forced out of the liquid and will instantly turn back into solid crystals at the bottom.
