In order to make an optical sensor for sensitive detection of hydrogen peroxide (i.e., in the concentration …
WebReactions involving electron transfers are known as oxidation-reduction reactions (or redox reactions). You may have learned in chemistry that a redox reaction is when one molecule loses electrons and is oxidized , while another molecule gains electrons (the ones lost by the first molecule) and is reduced . Web18. apr 2003 · However, the rate of the redox reaction may depend on the proton exchange kinetics. That will be the case for mechanism (IIb) where the concentration of the redox reactant DX − depends on the degree of the preceding electrolytic dissociation, and hence, if the dissociation equilibrium is not achieved, depends on the rate of proton transfer at ...
