Calculating bicarbonate from alkalinity
Webalkalinity is negligible: T = Bicarbonate alkalinity + Carbonate alkalinity (14) or T = Bicarbonate alkalinity + 2 P (15) Rearranging Eq (13): Bicarbonate alkalinity = T-2P (16) Equations (13) and (16) are shown in Table 1 for P < 1/2 T. As noted, however, these results are valid only for negligible hydroxide. As the pH value increases toward ...
