Model speciation of solute for large dataset
makerpaker posted a topic in The Geochemist's Workbench
Hi, I am wondering if there is a way for GWB to take a series of inputs at one time and generate the speciation results? For example, I have a dataset which has 2000 data. Can GWB take these data at once? Thank you very much. -
Hello, I am interested in calculating the charge balance of some chemical analyses and representing them graphically (e.g. with a pie graph in units of meq). The question I have is how to represent species that can be present in multiple valences (e.g. Fe). The default for Fe in GSS is as Fe+++, which is likely to be true for some of my samples, but not all. Do I need to do a SpecE8 run first and specify some kind of redox conditions in order to have Fe as both Fe++ and Fe+++? This question would apply to other elements with multiple charge states. When I calculate charge balance within the GSS program, is a speciation calculation run for the solution? Thanks, Spencer

I want to draw the speciation diagram for an aqueous solution which contains Gluconate complex ions and zinc cations over a pH range of 3 to 5. The software that I have downloaded does not have react included. Does any one know how I can draw this curves using GWB student? Many thanks for your hepl.

Hello, I am trying to plot a speciation diagram with Fe(II) in solution over a wide range of pH. The plot essentially needs to be a concentration (of various Fe(II) species) v pH. I watched a tutorial video on youtube which goes over doing such a plot with the React module. (link below) However, since I have the student edition, this module is not available. I would like to know if this sort of a diagram can be constructed with the modules that come with the student edition. I have already tried the specE8 module. However, this lets me specify only one pH at a time. Would it be okay to use this module to run the speciation multiple times at various pH and then use another graphing software to plot the numbers I get after every individual iteration? Any help is appreciated. Thanks in advance! Youtube link with speciation tutorial using React module:
