氧化还原反应规律（Oxidation reduction reaction law） The law of oxidation and reduction..txt gets up every morning to see the Forbes rich list. If it doesnt have my name, Ill go to work. Talk about money, not hurt feelings, talk about feelings, the most fucking hurt money. I curse you buying instant noodles all your life without seasoning bags. I. The Law of two strong and two weak: For spontaneous redox reactions (except for high temperature and electrolysis conditions), strong oxidizing substances and strong reducing substances react to form weakly oxidizing substances and weakly reducing substances. That is, the oxidation of oxidants is stronger than the oxidation of oxidation products, and the reducibility of reducing agents is stronger than the reducibility of reducing products. There are two applications: 1, determine the relative strength of particle oxidation and reduction. For example: (93) according to the reaction: (1) 2Fe3++2I=2Fe2++I2, (2) Br2+2Fe2+=2Br+2Fe3+, reductive ions can be judged from strong to weak order A.Br, Fe2+, IB.I, Fe2+, br C.Br, I, Fe2+ I, D.Fe2+, br 2, determine whether the redox reaction can occur. For example: Fe2+, SO2, I known, and H2O2 have reduced the CL, reducing their strength in acid solution in order ClFe2+H2O2ISO2, then the following reaction can occur is A.2Fe3++SO2+2H2O=2Fe2++SO42+4H+ B.I2+SO2+2H2O=H2SO4+2HI C.H2O2+H2SO4=SO2 = +O2 = +2H2O D.2Fe2++I2=2Fe3++2I Two, high oxygen, low return, middle and secondary rule For atoms with different valence states of the same species, the highest valence states are only oxidation, and the lowest valence states are reducible, and the intermediate valence states are both oxidizing and reductive. For example: S elements Valence 2 046 Stands H2S, S, SO2, H2SO4 (concentrated) The properties of S elements are redox, redox and oxidizing Three, the single from the strong weak, strong from the strong law 1, the stronger the reducibility of the metal elements, the weaker the oxidation of the correspondi
