Question

guys,what is meant by effervesence and efflorescence​

Answer 1

Effervescence is the escape of gas from an aqueous solution and the foaming or fizzing that results from that release. The word effervescence is derived from the Latin verb fervere, preceded by the adverb ex. It has the same linguistic root as the word fermentation.

Efflorescence is the migration of a salt to the surface of a porous material, where it forms a coating. The essential process involves the dissolving of an internally held salt in water, or occasionally in another solvent.
