Question:

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

Cl⁻andClO⁻

Cl⁻andClO⁻

ClO⁻andClO⁻

ClO⁻andClO⁻

Solution:

2NaOH(cold)+Cl₂→NaCl+NaClO+H₂O
The products obtained when chlorine gas reacts with cold and dilute aqueous NaOH are Cl⁻ and ClO⁻. Hence, option A is the correct answer.
