webmaster Posted November 8, 2004 Share Posted November 8, 2004 From: Andy Wilde Subject: Species with O2(aq) I am attempting to simulate the interaction between an hypothetical ore-forming brine and a shale-like host-rock at 200 degC. My question concerns the plotting of species with O2(aq). As the attached plot shows (*.cgm) a number of species are plotted that do not contain O2(aq). Can anyone explain why this is? From: Craig Bethke Subject: Re: Species with O2(aq) The species in your plot do indeed contain O2, but in negative amounts. For example, H2S(aq) = SO4-- + 2 H+ - 2 O2(aq). There is a discussion in the green book on the choice of components and why components can be present at negative mass. Quote Link to comment Share on other sites More sharing options...
