WebAn oxidation–reduction or redox reaction is a reaction that involves the transfer of electrons between chemical species (the atoms, ions, or molecules involved in the reaction). Redox reactions are all around us: the burning of fuels, the corrosion of metals, and even the processes of photosynthesis and cellular respiration involve oxidation and reduction. WebHowever, the type of buffer used in redox assays is critical for experimental outcome. In a standardized Fenton system (Fe 2+ + H 2 O 2 → Fe 3+ + • OH + OH – ), which is part of the Haber-Weiss reaction, (12) redox reactions proceed best in Tris- and HEPES-buffered solutions, indicating that these are preferred buffers for similar ...
