SED: Simple Equilibrium Diagrams

SED is a modified version of the Haltafall computer program. SED can generate fraction, logarithmic and solubility diagrams. Calculated values of pH and redox potential (pe) can also be plotted. In these diagrams, the calculated concentrations are plotted as a function of a master variable (usually pH, redox potential or a total concentration).
