answered-by-expert Expert Answer
Efflorescence: Crystalline hydrated salts which on exposure to the atmosphere lose their moisture (water of crystallisation) partly or completely to the atmosphere and change into the amorphous state. Examples: Washing soda (Na2CO3.10H2O), Glauber salt (Na2SO4.10H2O).
