The values of the acidic constants of CO2, pK01, in aqueous glucose solution were determine from emf measurements utilizing an improved Harned extrapolation and the polynomial approximation proposed by the authors. The values of pK01 obtained by both methods are in agreement with experimental methods. The dependence of first acidic constant on temperature is given by the empirical equation pK01 = A1 + A2/T + A3/T. The thermodn. of the first dissociation of CO2 in aqueous glucose solution were calculated
