The oxidation of NH4* to NO3 in acid solution (pH = 5.600) is described by the following equation:
%3D
NH(ag)+20,(g)
→ NO, (ag) +2H*(aq)+H,0(1)
The overall reaction for the oxidation has an E°cell = -0.2710 V.
E° = 1.50 V for the half-reaction
NO, (ag) + 10H* (aq) + 8e → NH(aq) +3H,0(1)
i See Periodic Table
Be sure to solve the equation using a base-10 logarithm (log) rather than the natural logarithm (In).
What is the ratio of [NO3] to [NH4*] at 298 K if Po2 = 0.180 atm? Assume that the reaction is at equilibrium.
