only species > 1e-8 molal listed --> all needed

Hi,

I would like to evaluate how the aqueous Fe(III) concentration in a mineral solution changes with pH (5-8).

Although the concentration of aqueous Fe(III) will be quite low I need to calculate exact values and thus would like React to give the full output and not crop values smaller than 10E-8 molal. How is that done?

For the initial setup simply giving the required concentrations and adding the sliding pH should do, right? Fe(III) is added as an aqueous species but should turn to be poorly soluble so I do not see what I am doing wrong there.

Thanks for your suggestions.

In React (as well as the SpecE8 and XT modules), go to the Config menu, and choose Print Options. Change Aqueous Species to long.

Yes, your approach is correct. It's difficult to know what the problems are with your output without seeing your script. Can you attach this?

that worked well now as all the needed concentrations are now included in the output file.

With the script itself I did not have any trouble, just accessing the data that should be ok now.

Thanks again
