Alkalinity - Wikipedia
Alkalinity - Wikipedia

Alkalinity, (from Arabic "al-qalī") is the capacity of water to resist acidification. It should not be confused with basicity which is an absolute measurement on the pH scale.. Alkanity is the strength of a buffer solution composed of weak acids and their conjugate bases.It is measured by titrating the solution with an acid such as HCl until its pH changes abruptly, or it reaches a known ...
