Can you get redox potential from dissolved oxygen in water?

  1. Nov 12, 2011 #1
    Hi there,

    I am trying to get the Eh (or pe) of water samples which I took last summer. I didn't measure it directly at the time. I do have dissolved oxygen values from each site. Is there a way to convert dO2 into Eh? All the dO2 values were in the 80-100% range.

    Alternatively, is there a way to convert dO2 into oxygen fugacity?

    I am hoping to make phase diagrams for the speciation of dissolved metals in a river.

    Sounds like you should use Nernst equation.
