Question

Define deliquesence and efflorescence

Answer 1

EFFLORESCECENCE
This is when certain solid substances, when exposed to air absorb water, enough to form solutions. Example, solid NaOH, CaCl2, CaCl2. 6H2O, P4O10 (forms HPO3), FeCl3, KOH, MgCl2

DELIQUESENCE
When some substances are exposed to air, they lose water to the atmosphere, thereby reducing in weight. Solids that behave in this way are those with water of crystallization. The molecules of water of crystallization are partially or completely lost to the atmosphere, thereby making them lose their crystalline forms.

Example, Na2SO4

Answer 2

deliquescence is the property of the liquid to overcome the state if chemiscal compoition and efflorescence substance means the liquid effolebsb the substance
