9/6/2012, · Sulphate reduction also takes place, which generates alkalinity, and can precipitate some metals as sulphides. However, alkaline addition in RAPS is dominated by the ,limestone, dissolution pathway. The ,acid neutralization, potential afforded by a RAPS ranges from 35 to over 400 mg/L CaCO 3.

LHS Principles of Chemistry - Alkalinity & Hardness in Water

Alkalinity should not be confused with pH. The pH of a solution is a measure of the concentration ,of acid,, or H + ions, in the water. Alkalinity is a measure of the water’s capacity to neutralize an ,acid,, or H + ions, thereby keeping the pH at a fairly constant level.. The alkalinity of surface water is primarily due to the presence of hydroxide, OH –, carbonate, CO 3 2–, and bicarbonate ...

Since carbonic ,acid, is a weak ,acid,, it tends to stay in its un-ionized state, so the pH of the water remains neutral. The general formula for alkalinity derived from a titration is: Example: A 100 mL sample of water is tested for alkalinity. The normality of the sulfuric ,acid, used for titrating is 0.02N.
