Oxidizing and Reducing Agents. A reducing agent is thus oxidized when it loses electrons in the redox reaction. Zn(s) -----> Zn^2+(aq) + 2e. Lv 4. There is a chemical reaction in which the oxidation states of the atoms vary. Oxygen pulls electrons away from other parts of the molecule, effectively oxidizing the entire molecule. Evaluate the equivalent weight of oxidizing and reducing agents in the following reaction (4M) K2Cr2O7 + FeSO4 > Cr3+ + Fe3+. Answer Save. So, it acts as both an oxidising and reducing agent. In a corrosive process, the anode oxidizes and the cathode reduces. And so before you assign oxidizing and reducing agents, you need to assign oxidation states. 3. An oxidizing agent can be compared to a reducing agent, or a chemical which causes another molecule to gain electrons.
