WebSep 14, 2024 · When titrating weak bases, water is always a reactant in this initial step, and its conjugate base, hydroxide, in the products. Table 1. ICE table at initial conditions. Drawing a chart like the one above is a useful step in calculating the concentration of hydroxide before any acid is added. WebThe titration of hydroxide is only important in water samples with very high pH, say greater than pH 9.2. Gran's method can be used to quantify negative values of alkalinity in solutions with an initial pH lower than the bicarbonate equivalence point. It is the only method available in the Alkalinity Calculator that can do so.
