Sub Topic Name : Equilibrium Involving Dissolution Of Solid Or Gases In Liquids |
|
Introduction
• Dissolution of gases in liquids follows henry’s law which states that the mass of a gas dissolved in a given mass of a solvent at any temperature is proportional to the pressure of the gas above the solvent.
Pre-Requisites:
Solid, gases, equilibrium, dissolution
Activity:
• When a soda water bottle is opened, some of the carbon dioxide gas dissolved in it fizzes out rapidly.
Real Life Question:
Why does sugar recrystallizes at low temperature?
