Redox Reactions And Electrochemistry Ques 12

Question: In alkaline medium $C l O_{2}$ oxidize $H_{2} O_{2}$ in $O_{2}$ and reduced itself in $C l^{-}$ then how many mole of $H_{2} O_{2}$ will oxidize by one mole of $C l O_{2}$ [Kerala CET 2005]

Options:

A) 1.0

B) 1.5

C) 2.5

D) 3.5

E) 5.0

Show Answer

Answer:

Correct Answer: C

Solution:

$C l O_{2} \to C l^{-}$

$C l O_{2} + 2 H_{2} O + 5 e \to C l^{-} + 4 O H^{-}$

$H_{2} O_{2} \to O_{2}$

$H_{2} O_{2} + 2 O H^{-} \to O_{2} + 2 H_{2} O + 2 e$

$C l O_{2} + 2 H_{2} O + 5 e \to C l^{-} + 4 O H^{-}] \times 2$

$H_{2} O_{2} + 2 O H^{-} \to O_{2} + 2 H_{2} O + 2 e] \times 2$

$2 C l O_{2} + 5 H_{2} O_{2} + 2 O H^{-} \to 2 C l^{-} + 5 O_{2} + 5 H_{2} O$

$2 C l O_{2} \equiv 5 H_{2} O_{2}$

$∴$ $C l O_{2} = 2.5 H_{2} O_{2}$
