2 MnO_4^-+ bI^-+ cH_2O xI_2+ yMnO_2+ zOH^- If the above equation is balanced with integer coefficients, the value of z is______

Question

Accepted Answer

Correct answer: 8. (8) Reduction Half Oxidation Half (2 MnO_4^- 2 MnO_2 2I^- I_2+2e^-) 2 MnO_4^-+4H_2O+6e^- 2 MnO_2+8 OH^-6I^- 3I_2+6e^- Adding oxidation half and reduction half, net reaction is 2 MnO_4^-+6I^-+4H_2O 3I_2+2 MnO_2+80H^- ⇒ (z=8 ) ⇒ Ans8
