WebbReducing Agent Oxidizing Agent e- e- e- e- e- e- Anode Cathode 33. Oxidizing agent pulls the electron. Reducing agent pushes the electron. The push or pull (“driving force”) is called the cell potential Ecell Also called the electromotive force (emf) Unit is the volt(V) = 1 joule of work/coulomb of charge Measured with a voltmeter WebbSo oxidation number of Cr in K2Cr2O7 is +6. Why K2Cr2O7 is strong oxidizing agent in acidic medium? In acidic medium, Cr undergoes a decrease in oxidation state from +6 in Cr2O2-7 ion to +3 in Cr3+ ion. Since +3 oxidation state is more stable than +6 oxidation state therefore, K2Cr2O7 is a good oxidising agent in the acidic medium. cooking words for home improvementWebbThe KMnO4 is stronger oxidizing agent than k2Cr2O7 because due to its higher reduction potential since as we know that the compound having higher reduction potential behaves as best oxidizing agent .
