Hydrogen peroxide oxidises [Fe(CN)6]4−[Fe(CN)_6]^{4-}   to [Fe(CN)6]3−[Fe(CN)_6]^{3-}   in acidic medium but reduces [Fe(CN)6]3−[Fe(CN)_6]^{3-}   to [Fe(CN)6]4−[Fe(CN)_6]^{4-}   in alkaline medium. The other products formed are, respectively:

  • A.H2OH_2O   and (H2O+O2)(H_2O + O_2)Correct
  • B.H2OH_2O   and (H2O+OH−)(H_2O + OH^-)
  • C.(H2O+O2)(H_2O + O_2)   and H2OH_2O
  • D.(H2O+O2)(H_2O + O_2)   and (H2O+OH−)(H_2O + OH^-)
