What Is The Difference Between Efflorescence And Deliquescence?
The difference between efflorescence and deliquescence is as follows,
Efflorescence | Deliquescence |
Efflorescence refers to losing the water of crystalline molecule when exposed to air at ordinary temperature. | Deliquescence is the process by which a chemical substance aborbs moisture from the atmosphere and dissolved in it to form solution. |
Efflorescence occurs when the aqueous vapour pressure of the hydrate is greater compared to the partial pressure of the water vapour in the air. | Deliquescence occurs when the vapour pressure of the solution that is formed is less compared to the partial pressure of water vapour in the air. |
Example: Washing soda(Na2CO3.10H2O) which loses nine water molecule and after sometime loses all ten water molecule to convert in anhydrous form. | Example: Sodium hydroxide(NaOH), Potassium hydroxide(KOH) |
