Ecorm-A PC program as a support to graphical methods.

A computer-graphics program applicable to the treatment of experimental data of equilibrium analysis is described. The program admit up to 500 experimental points referring to system involving up to 3 reagents. Although it doesn' t work out statistics from data and doesn' t start from preliminary hypotheses on species and values, it is able to draw conclusions on the prevailing species, the value of their stability constants and their field of existence by means of a kind of representation of the data similar to the graphic approximation of a curve to experimental points. The proposed program compares favourably as to speed and objectivity with resect to t5he graphical methods. A comparison between values obtined by graphical methods and by the proposed program supports its utility and validity.
