Hyperquad simulation and speciation (HySS): a utility program for the investigation of equilibria involving soluble and partially soluble species

Hyperquad simulation and speciation (HySS) is a computer program written fo r the Windows operating system on personal computers which provides (a) a s ystem for simulating titration curves and (b) a system for providing specia tion diagrams. The calculations relate to equilibria in solution and also i nclude the possibility of formation of a partially soluble precipitate. The re are no restrictions as to the number of reagents that may be present or the number of complexes that may be formed. (C) 1999 Elsevier Science S.A. All rights reserved.
