==Origin==
[[Latin]] ''effervescere'', from ''ex- + fervescere'' to begin to [[boil]], inchoative of ''fervēre'' to boil
*[http://en.wikipedia.org/wiki/18th_century 1784]
==Definitions==
*1: to bubble, hiss, and foam as [[gas]] [[escapes]]
*2: to show liveliness or exhilaration
==Description==
'''Effervescence''' is the [[escape]] of [[gas]] from an [[Water|aqueous]] solution and the foaming or fizzing that results from a release of the [[gas]]. An everyday example is seen in [http://en.wikipedia.org/wiki/Carbonation carbonated beverages] such as soft drinks. The visible bubbles are produced by effervescence from the dissolved gas (which itself is not visible in the [[liquid]] solution).
In the [[laboratory]], a common example of effervescence is seen if [http://en.wikipedia.org/wiki/Hydrochloric_acid hydrochloric acid] is added to a block of [http://en.wikipedia.org/wiki/Limestone limestone]. If a few pieces of marble or an antacid tablet are put in hydrochloric acid in a test tube fitted with a bung, effervescence of carbon dioxide can be witnessed.
This [[process]] is generally [[represented]] by the following [[reaction]], where a pressurized dilute solution of carbonic acid in water releases gaseous carbon dioxide at [http://en.wikipedia.org/wiki/Decompression decompression]:
:H2CO3 → H2O + CO2
In [[simple]] terms, it is the result of the [[chemical]] [[reaction]] occurring in the [[liquid]] which produces a [[gaseous]] product.
