WebDuring this process, a constant potential is applied to the working electrode and current is monitored over time. The analyte in one oxidation state will be oxidized or reduced to another oxidation state. The current will decrease to the base line (approaching zero) as the analyte is consumed. WebRedox potential (Eh) is the measurement of the tendency of an environment to oxidize or reduce substrates. An aerobic soil, which is an oxidizing environment, has an Eh of+800 mV; an anaerobic soil, which is a reducing environment, has a negative Eh which can reach −300 mV. Oxygen is found in soils at a redox potential of about+800 mV.
