The water dissociation equilibrium constant, Kw, and the first acid dissociation constant of H28, Ki, are both well documented. 8everal studies have confirmed that K2, the second acid dissociation constant of H28, has a value of 10 [38-43], and not as previously assumed 10 [38]. This results in a substantial revision of known metal sulfide solubilities [44]. Noticeably, the concentrations of...

Sn, Sr, Te, Th, Ti, U, V, W, and Zn) are being semi-critically reviewed by Donald Langmuir and Hugh Barnes of Pennsylvannia State University with NBS funding. Polysulfide complexes are to be included in their review. The status of the thermodynamic data on sulfide- and polysulfide-metal complexes will also be discussed in a revised edition of "Hydrothermal Ore Deposits" edited by Hugh Barnes (15). 

The computerized aqueous chemical model of Truesdell and Jones (, 3), WATEQ, has been greatly revised and expanded to include consideration of ion association and solubility equilibria for several trace metals, Ag, As, Cd, Cu, Mn, Ni, Pb and Zn, solubility equilibria for various metastable and(or) sparingly soluble equilibrium solids, calculation of propagated standard deviation, calculation of redox potential from various couples, polysulfides, and a mass balance section for sulfide solutes. Revisions include expansion and revision of the redox, sulfate, iron, boron, and fluoride solute sections, changes in the possible operations with Fe (II, III, and II + HI), and updating the model s thermodynamic data base using critically evaluated values (81, 50, 58) and new compilations (51, 26 R.

A sequence of iron mineral reactivity towards sulfide was proposed more than 10 years ago (Canfield et al. 1992), which was later extended (Raiswell and Canfield 1996), and recently revised (Poulton et al. 2004). The revised sequence particularly accounts for the mineral surface area and can be grouped into two fractions excluding...

The high-temperature condensation of aromatic halides (diphenylsulfide, thian-threne, diphenyldisulfide, thiophenol and direct reactions of benzene with sulfur) in the presence of aluminium chloride was examined by Sergeyev et al. [98]. The reaction of 1,4-dichlorobenzene or 1,4-dibromobenzene with sodium sulfide at 195 °C in N-methylpyrrolidone (NMP) has been studied under normal atmospheric pressure, the kinetic of polymerization was found to be of second order. The same reaction in NMP was revised by Russian authors [99]. The polymerization of diphenyldisulfide produced PPS when stoichiometric amounts of diphenyldisulfide and antimoniumpentachloride were used in nitrobenzene at 20 °C. The S-S bond cleavage is catalyzed by the Lewis acid and the authors claim to have obtained an identic product compared with the commercial one with a molecular weight >1000 [100].
