SED & PREDOM |
PREDOM is a program to calculate and draw predominance area diagrams. Such a diagram shows which of the aqueous species, that are formed by a given main component (usually a metal cation), dominate at a given point (i.e., at given concentrations of the ligand components). For solid phases, a predominance area diagram shows the range of existence for solids formed by the main component. Therefore, it shows where a solid phase is thermodynamically stable (even if the amount of solid formed at equilibrium is perhaps very small).
This program can draw diagrams with either
