− | '''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). | + | '''Effervescence''' is the [[escape]] of [[gas]] from an [[Water|aqueous]] solution and the foaming or fizzing that results from a release of the [[gas]].

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. | + | In the [[laboratory]], a common example of effervescence is seen if [https://en.wikipedia.org/wiki/Hydrochloric_acid hydrochloric acid] is added to a block of [https://en.wikipedia.org/wiki/Limestone limestone].
