The products obtained when chlorine gas reacts with cold and dilute aqueous `NaOH` are :

Options

A. `ClO_(2)^(-)` and `ClO_(3)^(-)`
B. `Cl^(-)` and `ClO^(-)`
C. `Cl^(-)` and `ClO_(2)^(-)`
D. `ClO^(-)` and `ClO_(3)^(-)`

Answer

B

Explanation

`underset("Cold & dil.")(Cl_2 + 2NaOH) to Cl^(-) + ClO^(-) +Na^(+) +H_(2)O`
Disproportional reacation
