Input acidimetric titration data and other information in the form below. Fields shown in red are required. The Alkalinity Calculator will analyze the titration curve and calculate the alkalinity or acid neutralizing capacity (ANC) of the sample using one or more of several different methods. Alkalinity is for filtered samples, while ANC is for unfiltered samples. The results will be displayed in tabular and graphical form.
Send comments, questions, and suggestions to firstname.lastname@example.org. Please send me any datasets that appear to cause problems for the Alkalinity Calculator.
Note: The specific conductance is used to estimate the ionic strength of the sample. Ionic strength and sample temperature are used to calculate the equilibrium dissociation constants of water and carbonic acid, which are then used in the calculation of hydroxide, carbonate, and bicarbonate concentrations. If you know the sample's temperature and specific conductance, please input them. If these data are unavailable, default values will be assumed.
