An appropriate replacement for oxygen in water

  1. Jul 25, 2011 #1
    I am trying to model the behavior of oxygen in water. However there is so little oxygen in water I don't think I could measure concentrations of it experimentally.

    Does anyone have advice on what I might be able to use as a replacement for oxygen?

    I need to find something (a gas?) that is more soluble in water then oxygen, which is of similar size to O2, which I can more easily measure experimentally.

    Thanks!
