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: ? = ?o -? x Sqrt(c) wherein ? is the molar conductivity, ?o is the molar conductivity at infinite dilution, c is the concentration, and K is the coefficient, and wherein K and ?o are predetermined values for K and ?o for each ionic species, (iii) calculating the conductivity ? for each ionic species by the formula: ? = c x ? 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. |
