Example Calculation, pe-pH

Because all pe-pH calculations are similar, we will only use one example to illustrate the general method. [Pg.489]

In the above section on Eh, we showed that the boundary Mn(0H)2 Mn304 can be described by the equation [Pg.490]

This could be used to calculate an equation for the same boundary in the variables pe and pH from relationship (18.44)  [Pg.490]

Substituting (18.44) into (18.24) does reproduce the pe-pH equation (18.45) exactly, showing that the two variables Eh and pe are interchangeable for practical purposes and you can choose whichever you prefer to calculate redox boundaries. [Pg.490]

In the above treatment of the variable pe, we began with the definition [Pg.490]
