acidification
Turning more acidic
Acidification is the process of becoming more acidic—lowering pH through the addition of acid or acid-forming substances.
The term appears most often in environmental contexts: ocean acidification from absorbed carbon dioxide threatens coral reefs and shellfish.
Soil acidification affects agriculture.
In food science, acidification preserves or flavors: the acidification of milk to make cheese.
