Ph Diagram For Nitrogen. A reference quality thermodynamic property formulation for nitrogen j. While under oxidizing conditions eh 400 mv nitrogen is generally in the form of no 3.
It is noted that nh 4 is the most abundant species in groundwater when 500 mv eh 300 mv at ph 923. The thermodynamic data for important nitrogen species are given in table 7. What you need to know.
The scientists used units of ug g 1 for the concentration of ammonia in soil.
Data 29 61361 1433 2000. At higher potentials a further oxidation to nio 2 with a new decrease in current is observed. The calculated diagram was verified by measuring the potential of the silver electrode at ph values varying from 2 to 12. 24 23 carbon dioxide p h diagram span r.
