| acid dissociation constant |
In chemistry and biochemistry, acid dissociation constant, the acidity constant, or the acid-ionization constant (Ka) is a specific type of equilibrium constant that indicates the extent of dissociation of hydrogen ions from an acid. While strong acids dissociate practically completely in solution and consequently have large acidity constants, weak acids do not fully dissociate and generally have acidity constants far less than 1. ...

| acid rain |
Acid rain is defined as rain with a pH of below 5.6. Normal rain has a pH of slightly under 6, which is slightly acidic. This natural acidity is caused by dissolved carbon dioxide dissociating to form weak carbonic acid. 'Acid rain' is caused by sulphur from impurities in fossil fuels, and nitrogen from the air combining with oxygen to form sulphur dioxide and nitrogen dioxide. ...
