Class 12th "Solutions" Chapter 02

SOLUTIONS OF SOLIDS IN LIQUIDS : 

•  Saturated Solutions :  A solution that contains maximum amount of a solute in a given solvent at room temperature. No more solute can dissolve in it. It is a dynamic equilibrium between the undissolved and dissolved solute this is called saturated solution. 

( वह विलयन जिसमें किसी निश्चित ताप पर और अधिक विलेय को घोलना असंभव हो।) 

•  Dissolution :  जब एक solid को liquid में dissolve किया जाता है तो molecular vebrations solute molecules को solution मे enter करने के लिए बाध्य करते हैं। 

•  Precipitation : जैसे जैसे liquid state में solute molecules के concentration में बढ़ोतरी होती जाती है solute molecules solid state मे वापस आना शुरू कर देते हैं। 

•  Unsaturated Solutions :   A solution that is capable of dissolving more solute at a given temperature that it already contains it is known as unsaturated solutions. 

        

•  Supersaturated Solutions :  A solution that contains more dissolved substances that a saturated solution is called supersaturated solution. 

Solubility :  Saturation defines the solubility of solute. 

"Solubility is the maximum amount of solute that can be dissolved in a given solvent."



Difference between saturated, unsaturated and supersaturated solutions : 

Practice Questions : 

1. What do you understand by supersaturated solutions. 

2. What is difference between saturated solution and unsaturated solutions. 

3. Write down the examples of saturated, supersaturated, unsaturated solutions.
