For the portion of the pE-pH diagram where the reduction of NO2 - to NH4 + is the relevant reaction, use the expression (NO2- + 8H+ + 6e- → NH4+ + 2H20 and pE=15.14-log([NH44]⅙ /[NO2- ]⅙ [H+]4/3])) to find the equation for the line that will separate the two species. Remember that the line will be where the species are equal in concentration. (Hint: your equation should be in the form y = mx + b where y = pE...
