Webponent carbonate electrolyte systems can be predicted. From solubility constants to Gibbs functions and back again: The original method for the determination of standard Gibbs functions of (divalent) metal car- bonates is based on measurements of electrode potentials a.nd solubilities by “pH-variation” [lo]. WebThe titration involved in the determination of the carbonate content is an example of a weak base being titrated with a strong acid. The two weak bases involved are CO2 − 3 with Kb1 = 2.1 × 104 and HCO − 3 with Kb2 = 2.4 × 10 − 8. The reactions involved are: CO2 − 3 + H3O + ⇌ HCO − 3 + H2O. and. high long kitchen cabinet
