Chemical oceanography of the Arabian Sea: Part II - Equilibrium of inorganic nitrogen system
Abstract
The concept pE, expressed as a dimensionless quantity to study the redox potential of a system at equilibrium, is applied to study the chemistry of the system NO-<sub>3</sub>-NO-<sub>2</sub>NH+<sub>4</sub> in the northern Arabian Sea. Values observed are found to be close to the equilibrium values calculated from theoretical relations and are nearer to the more recent concept of the normal value for sea water.It is inferred that the system approaches equilibrium conditions in the deeper waters of the oceans along with the O<sub>2</sub>H<sub>2</sub>O<sub>2</sub> couple.
