Observe the following reaction
\(\mathrm{Cl}_2(\mathrm{~g})+2 \mathrm{OH}^{-}(\mathrm{aq}) \rightarrow \mathrm{ClO}^{-}(\mathrm{aq})+\mathrm{Cl}^{-}(\mathrm{aq})+\mathrm{H}_2 \mathrm{O}(\mathrm{l})\)
Identify the correct statements about this reaction
I. \(\mathrm{Cl}_2(\mathrm{~g})\) is oxidized to \(\mathrm{ClO}^{-}\)(aq)
II. \(\mathrm{Cl}_2(\mathrm{~g})\) is oxidized to \(\mathrm{Cl}^{-}(\mathrm{aq})\)
III. \(\mathrm{Cl}_2(\mathrm{~g})\) is reduced to \(\mathrm{ClO}^{-}\)(aq)
IV. \(\mathrm{Cl}_2(\mathrm{~g})\) is reduced to \(\mathrm{Cl}^{-}(\mathrm{aq})\)
The correct answer is
- A I, IV only
- B I, III only
- C I, II, IV only
- D II, III only
Answer & Solution
Correct Answer
(A) I, IV only
Step-by-step Solution
Detailed explanation
In the given reaction, \(\mathrm{Cl}_2\) is getting disproportionated into +1 state in \(\mathrm{ClO}^{-}\)and -1 state in \(\mathrm{Cl}^{-}\). \(\mathrm{Cl}_2\) to \(\mathrm{ClO}^{-}\)is oxidation while \(\mathrm{Cl}_2\) to \(\mathrm{Cl}^{-}\)is reduction.
