This lecture covers the construction of pe-pH diagrams for redox-sensitive elements, focusing on the example of nitrogen species stability. It explains the calculation of pe-pH relationships for various redox reactions and the significance of stability diagrams in understanding speciation. The lecture also discusses the co-occurrence of iron and nitrate in groundwater and the kinetics of abiotic nitrogen reactions. PHREEQC examples are used to illustrate the calculations and equilibrium conditions.
