How do you measure the alkalinity of water in a titration?
Alkalinity is usually measured using sulfuric acid with a digital titrator.
Sulfuric acid is added to the water sample in measured amounts until the three main forms of alkalinity (bicarbonate, carbonate, and hydroxide) are converted to carbonic acid.Typical indicators used are phenolphthalein and methyl orange.
The volume of acid consumed during the titration can be used to determine the strength of various alkalinity causing ions.13 juil. 2023
What is the method of determination of alkalinity in water?
Total alkalinity is measured by collecting a water sample, and measuring the amount of acid needed to bring the sample to a pH of 4.2.
At this pH all the alkaline compounds in the sample are "used up." The result is reported as milligrams per liter (mg/l) of calcium carbonate.
What is the titration test for total alkalinity?
This method involves titration, the addition of small, precise quantities of sulfuric acid (the reagent) to the sample until the sample reaches a certain pH (the endpoint).
The amount of acid used corresponds to the total alkalinity of the sample.
Digital titrators have counters that display numbers.
