The complexed dye would have a different reduction potential compared to the uncomplexed dye. Recently indium has been detected by DPP following adsorption of the In 1-(2-pyridylazo)-2-naphthol complex on napthalene in the pH range of 6.5–11.5. The quoted detection limit being 2×10−6 ...
Microcosms established with El Verde tropical soil amended with lactate consumed N2O at pH 4.5; however, N2O-reducing activity was lost upon transfers to vessels with fresh medium containing lactate. The addition of acetate, formate (1 or 5 mM each), and CO2 (208 µmol, 2.08 mM nom...
Different Redox Potentials and pH Values in Different Foods The redox potential of food depends on its chemical composition, the treatment given and the storage conditions in relation to oxygen tension. For example, in fresh muscle foods, respiration in the tissue utilizes most of the remaining oxy...

As an alternative energy, hydrogen can be converted into electrical energy via direct electrochemical conversion in fuel cells. One important drawback of full cells is the sluggish oxygen reduction reaction (ORR) promoted by the high-loading of platinum-group-metal (PGM) electrocatalysts. Fe-N-C ...
When tap water is electrolyzed into ionized Water, its reduced water has a pH of about 9-10 and the oxidized water a pH of about 4-5. Even if you make alkaline water of pH 9 by adding sodium hydroxide or make acidic water of pH 3 by adding hydrogen chloride, you will find very ...
3.2 Using H2O Instead of H2 as a Hydrogen Source for Electrochemical Ammonia Synthesis at Low Temperature and Ambient Pressure Due to the in situ hydrogen evolution in the electrochemical cell during the nitrogen reduction reaction, it was possible to use H2O as a hydrogen source instead of H2,...
Understanding the ORR mechanism in this pH region is complex, as it involves biotic (living systems or components derived thereof) and abiotic (often inorganic materials or composite) catalysts. This review offers a summary of catalyst-class-dependent ORR mechanisms and pathways with the corresponding...
