Which of the following is incorrect for the reaction below? 6 1^- (aq) + 4 H_2O(1) + 2 MnO_4^- (aq) rightarrow 3 1_2 (aq) + 2MnO_2(s) + 8 OH^- (aq) The iodide ion serves as the reducing agent. The manganese in the MnO^-_4 ion has an oxidation state of +7. The oxygen and hydrogen atoms do not change oxidation state in this reaction. The manganese in MnO_2(s) has an oxidation state of +4. lodine has an oxidation state of +...
