Hello, I was trying to make a redox diagram for NO3 with 12 samples I have input into GSS. I have watched the video tutorial and was unsure what the activity should be and how they knew what values to put in. Clarification on what the activity value refers to would be appreciated. I am unsure if it is a standard value for each element (Ex: SeO3 is always 1.0e-6 and U++++ is always 10.0) or if it changes. Thanks, Ashley
