This paper deals with results obtained by the distribution method described in the preceding paper1 . This work still being in progress and new data may considerably change the present picture. For those interested in the chemistry of coordination co

An estimation of the annual decrease in alkalinity (At) in the Persian Gulf was calculated to be 0.326 × 1012 mol/yr and in the Red Sea 1.65 × 1012 mol/yr. Together this amounts to a loss of carbon as calcium carbonate of 12 Mton/yr which is about

Sulphur is an essential element for aquatic biosystems, the life processes of which lead to the formation of low molecular weight S compounds in the water. The results of our calculations indicate a pronounced tendency for Hg(II) to form HgS (or HgOH

Depth profiles for O2/H2S, Mn, Fe, Co, Ni, Cu and Cd are presented for the Gotland Deep, based on samples collected in 1981 and 1985. Stability constants (K1KSO) for the equilibrium MS(s) + H+ ⇌ M2+ + HS− have been calculated from the solubility

Since the activity of water varies only slightly in studies of equilibria in aqueous solutions, the studies give no proof of complexes including H 2 O (e.g., ZnOHSH and ZnOH(SH) 2 − ). Data on sphalerite given by Gubeli and Ste-Marie (1967) as well

Measurements of alkalinities and calcium concentrations in the Baltic Sea indicate that there has been a slight increase in both these parameters over the last century. These increases may have been caused by the leaching of limestone by acid rain. A
