Gases in a Salt Marsh: You measure appreciable CH 4(g) andCO 2(g) partial pressures in the sediment pore fluid and you want toknow if there is equilibrium between these redox couples. The measuredpartial pressure of CO 2 (g) is 1x10 -5 atm and the measured partialpressure of CH 4 (g) is 5x10 -3 atm in the pore fluid.You measure a redox potential (E h) of pore-fluid water of Eh = -0.1 V atpH=8.3 using a platinum electrode and suitable reference electrode. Calculate a value of E h from the ratio of the measured gas partialpressures

Question
Gases in a Salt Marsh: You measure appreciable CH 4(g) and
CO 2(g) partial pressures in the sediment pore fluid and you want to
know if there is equilibrium between these redox couples. The measured
partial pressure of CO 2 (g) is 1x10 -5 atm and the measured partial
pressure of CH 4 (g) is 5x10 -3 atm in the pore fluid.
You measure a redox potential (E h) of pore-fluid water of Eh = -0.1 V at
pH=8.3 using a platinum electrode and suitable reference electrode.
Calculate a value of E h from the ratio of the measured gas partial
pressures
