Redox Reactions And Electrochemistry Ques 349

Question: In which of the following reactions $H_{2} O_{2}$ is a reducing agent-

Options:

A) $2 F e C l_{2} + 2 H C l + H_{2} O_{2} \to 2 F e C l_{3} + 2 H_{2} O$

B) $C l_{2} + H_{2} O_{2} \to 2 H C l + O_{2}$

C) $2 H I + H_{2} O_{2} \to 2 H_{2} O + I_{2}$

D) $H_{2} S O_{3} + H_{2} O_{2} \to H_{2} S O_{4} + H_{2} O$

Show Answer

Answer:

Correct Answer: B

Solution:

[b] ${\overset{0}{C l},}_{2} + H_{2} O_{2} \to + 2 \overset{- 1}{H C l}, + O_{2.}$ in this reaction chlorine is reduced from zero to -1 oxidation state.
