Ionic equilibria of pollutants

Table 10.2 gives the electrode reactions and standard electrochemical potentials (i.e., the half-cell Vs SHE, all ion concentrations = 1 M, all gases at 1 atm) of five common water-impurity species and three dissolved species that influence the stability of the impurities.

Example: Compare the effectiveness of nitrate ion for removing ethanol from water to that of oxygen.

Nitrate ion: The overall reaction is:

This reaction is the following combination of half-cell reactions A and 1:

Do we really want the one thing that gives us its resources unconditionally to suffer even more than it is suffering now? Nature, is a part of our being from the earliest human days. We respect Nature and it gives us its bounty, but in the recent past greedy money hungry corporations have made us all so destructive, so wasteful.
