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

(1) (H₂O + O₂) and (H₂O + OH^–)

(2) H₂O and (H₂O + O₂)

(3) H₂O and (H₂O + OH^–)

(4) (H₂O + O₂) and H₂O

Hydrogen peroxide oxidises [Fe(CN)6]^4– to [Fe(CN)6]^3– in acidic medium but reduces [Fe(CN)6]^3– to [Fe(CN)6]^4– in alkaline medium.
