Iodine reduction reaction
WebThe use of these two reagents, then, will enable a determination to be made of glucose and fructose when together in solution, or of glucose, fructose, and sucrose when these three sugars occur together. In the latter case, the determination of the reducing power of the sugar solution on both the iodine and copper reagents before hydrolysis of ... Webwhere the asterisk indicates the free site on the CE and “sol” indicates the electrolyte solvent. The solution reaction step I typically proceeds rapidly and in equilibrium, or the molecular iodine reduction reaction (IRR) steps II and III occurring at the CE/electrolyte interface are the rate-determining steps (21, 22).
