Similar to how the concentration of hydrogen ion determines the acidity or pH of an aqueous solution, the tendency of electron transfer between a chemical species and an electrode determines the redox potential of an electrode couple. Like pH, redox potential represents how easily electrons are transferred to or from species in solution. Redox potential characterises the ability under the specific condition of a chemical species to lose or gain electrons instead of the … Web5. sep 2016 · In a thermally stratified lake, redox may fall very low – even to negative values – when DO concentration falls to 0 mg/L in the deeper (hypolimnetic) water. However, in aquaculture ponds that normally do not stratify thermally, the redox potential usually will be above 0.50 volt at the sediment-water interface because DO is present. pompano pines east bridgewater ma
