Determination of Carbonate Alkalinity in Natural Waters
This article discusses the Larson and Henley method for determining low alkalinities in rain water. The method increases the accuracy of the determination of carbonate alkalinity as it eliminates the error due to variation of true equivalence point with total alkalinity. The method determines the ac...

Summary: | This article discusses the Larson and Henley method for determining low alkalinities in rain water. The method increases the accuracy of the determination of carbonate alkalinity as it eliminates the error due to variation of true equivalence point with total alkalinity. The method determines the actual inflection point or equivalence point pH of the titration, and it has been adapted to routine use with no significant decrease in accuracy. The variation of equivalence point of the titration of bicarbonate ion to carbonic acid is graphically shown over a wide range of alkalinities. |
