Total alkalinity is determined by titration of the water sample to the endpoint of the methyl orange, bromocresol green, or bromocresol green–methyl red indicators, approximately pH 4.5.

How do you test water alkalinity?

Water alkalinity is measured by titrating a sample with a strong acid to a designated titration endpoint.
The endpoint is commonly determined using pH (visual) indicators.
Alternatively, a pH meter may be used.

What is the standard alkalinity of water?

Alkalinity should not be depressed below 20 mg/L as CaCO₃ for Class I and III-freshwaters and should be = 600 mg/L as CaCO₃ for agricultural water supplies.

How do you calculate the alkalinity of water?

Alkalinity(mg/L as CaCO3) = volume of acid consumed(mL) × molarity of acid(M) × 50 × 1000 volume of water sample(mL)._{13 juil. 2023}

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.
