Effervescence
Effervescence
Effervescence (pronounced: /ˌefərˈves(ə)ns/) is a term used in chemistry and medicine to describe the process of gas escaping from an aqueous (water-based) solution in the form of bubbles. The term is derived from the Latin word "effervescere", which means "to boil up" or "to bubble up".
Etymology
The term "effervescence" is derived from the Latin "effervescere", which is a combination of "ex-" (out) and "-fervescere" (to begin to boil), from "fervēre" (to boil). This term was first used in the English language in the late 17th century.
In Medicine
In medicine, effervescence is often observed in the reaction of antacid tablets in water. The gas produced, usually carbon dioxide, helps to neutralize stomach acid and relieve symptoms of conditions like heartburn and acid reflux. Effervescent tablets are also used in other types of medication for their quick absorption rate.
In Chemistry
In chemistry, effervescence is a common observation in acid-base reactions where a gas is produced. This is often seen in the reaction between a carbonate or a bicarbonate and an acid, where carbon dioxide is produced and escapes the solution as bubbles.
