Alkalinity - Wikipedia

2019-5-14 · Alkalinity (from Arabic "al-qalī") is the capacity of water to resist changes in pH that would make the water more acidic. ( It should not be confused with basicity which is an absolute measurement on the pH scale.) Alkalinity is the strength of a buffer solution composed of weak acids and their conjugate bases.It is measured by titrating the solution with a monoprotic acid such as HCl until
