In a method of preparing a liquid solution by mixing ingredients according to a predetermined recipe, wherein at least one pair of species of the liquid solution is derived from a weak electrolyte and corresponds to an acid-base pair, the conductivity of the liquid solution is predicted by: (i) for each pair of species derived from a weak electrolyte, solving a respective equilibrium equation to calculate the actual molar concentration of each such species at equilibrium in the liquid solution, (ii) calculating for each ionic species of said plurality of species the molar conductivity by the formula: Lambda=Lambda0-K×Sqrt(c) wherein Lambda is the molar conductivity, Lambda0 is the molar conductivity at infinite dilution, c is the concentration, and K is the Kohlrausch coefficient, and wherein K and Lambda0 are predetermined values for K and Lambda0 for each ionic species, (iii) calculating the conductivity x for each ionic species by the formula: kappa=c×Lambda and (iv) adding up the conductivities determined in step (iii) for the different ionic species to obtain a predicted conductivity of the liquid solution. A computer program product comprises instructions for causing a computer to perform the method steps. |
