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

Options

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

Answer

A

Explanation

With cold dilute aqueous NaOH, `Cl_(2)` forms chloride ion `(Cl^(-))` and hypochlorite `(OCl^(-))` ion.
`Cl_(2) + 2 OH^(-) rarr Cl^(-) + OCl^(-) + H_(2)O`
