Acidification

Part of speech: noun

Pronunciation: /əˌsɪdɪfɪˈkeɪʃən/

Definitions

1. The transformation of a solution occurs when its pH diminishes, resulting in increased acidity and altering chemical balance, which can have significant ecological consequences
2. A decline in a solution's pH level signifies a rise in acidity, often resulting in shifts in chemical properties and biological effects on living organisms
3. The process of lowering the pH of a liquid leads to increased acidity and can trigger changes in its chemical behavior and ecological impact on habitats

Etymology: Acidification is a textbook case of a scientific term built from familiar parts. It was borrowed from French, where "acidification" was formed from the stem of "acide" (acid) plus the suffix "-ification," which turns a base into a noun for the act of making something into that thing. English therefore took the word as a ready-made chemical label: the process of making something more acidic. The suffix does the real work here. Its pattern appears in older chemical vocabulary, such as "petrification" (turning to stone), and the same ending lets chemists describe any substance being converted into a different state or quality. Attach it to "acid" and you get a noun for the gradual shift toward acidity, which is why the word fits both a beaker experiment and the slow change in seawater.

Synonyms: sourness, tartness, acidic change
