acid reaction


Also found in: Encyclopedia.

ac·id re·ac·tion

1. any test by which an acid reaction is recognized, such as the change of blue litmus paper to red;
2. an excess of hydrogen ions over hydroxide ions in aqueous solution indicated by a pH value less than 7 (at 22°C). Compare: dissociation constant of water.
