- •
Endpoint pH for alkalinity titration decreases with greater alkalinity.
- •
An accuracy better than ± 3 mg l− 1 is possible in alkalinity analyses.
- •
Filtration does not improve accuracy of alkalinity analysis.
- •
Replicate alkalinity analyses had coefficients of variation < 5%.
- •
Interlaboratory tests of alkalinity standards revealed frequent inaccuracies.
