Question: Chlorine on reaction with hot and concentrated sodium hydroxide gives:
$\mathrm{Cl}^{-}$and $\mathrm{ClO}_{2}^{-}$
$\mathrm{Cl}^{-}$and $\mathrm{ClO}_{3}^{-}$
$\mathrm{Cl}^{-}$and $\mathrm{ClO}^{-}$
$\mathrm{ClO}_{3}^{-}$and $\mathrm{ClO}_{2}^{-}$
Correct Option: , 2
Solution:
$3 \mathrm{Cl}_{2}+6 \mathrm{OH}^{-} \rightarrow 5 \mathrm{Cl}^{-}+\mathrm{ClO}_{3}^{-}+3 \mathrm{H}_{2} \mathrm{O}$
