Question:

Chlorine on reaction with hot and concentrated sodium hydroxide gives:

  1. $\mathrm{Cl}^{-}$and $\mathrm{ClO}_{2}^{-}$

  2. $\mathrm{Cl}^{-}$and $\mathrm{ClO}_{3}^{-}$

  3. $\mathrm{Cl}^{-}$and $\mathrm{ClO}^{-}$

  4. $\mathrm{ClO}_{3}^{-}$and $\mathrm{ClO}_{2}^{-}$


Correct Option: , 2

Solution:

$3 \mathrm{Cl}_{2}+6 \mathrm{OH}^{-} \rightarrow 5 \mathrm{Cl}^{-}+\mathrm{ClO}_{3}^{-}+3 \mathrm{H}_{2} \mathrm{O}$
