Question

Hard

Solving time: 4 mins

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.

H_{2} O

and

(H_{2} O + O_{2})

H_{2} O

and

(H_{2} O + OH^{-})

(H_{2} O + O_{2})

and

H_{2} O

(H_{2} O + O_{2})

and

2 [Fe (CN)_{6}]^{4 -} + H_{2} O_{2} + 2 H^{+} ⟶ 2 [Fe (CN)_{6}]^{3 -} + 2 H_{2} O

2 [Fe (CN)_{6}]^{3 -} + H_{2} O_{2} + 2 OH^{-} ⟶ 2 [Fe (CN)_{6}]^{4 -} + O_{2} + 2 H_{2} O
