AN OBJECTIVE COMPUTER- ORIENTED METHOD FOR CALCULATION OF STABILITY CONSTANTS FROM FORMATION FUNCTION

A computer program written in Fortran IV language to calculate the stability constants of simple mononuclear complexes from formation function data was tested using literature data for the Cu (II) ammine, the Ni(II), Cu (II), and Zn (II) fluoride, the uranyl monochloroacetate, and the U (IV) bisulfate systems. The program was applied to the calculation of over-all stability constants using, first, n-ligand concentration data combined from several experimental techniques for measuring the Hf (IV) and Ta (V) fluoride complexes and, second, n-ligand concentration data for the aquo complexes in 1-butanol of Co (II) and Ni (II) obtained by the method of corresponding solutions. New conclusions were reached concerning the nature and stabilities of several of these complex ion systems in both the test series and the final series of calculations. © 1969, American Chemical Society.
