  1. Question 1

    Q1. Chlorine gas is bubbled through a cold, dilute aqueous solution of Sodium hydroxide. What are the products of this disproportionation reaction?

    • A) Sodium chlorate and NaCl
    • B) Sodium hypochlorite and NaCl
    • C) Sodium perchlorate and NaCl
    • D) Chlorine dioxide and NaCl

    Answer: Sodium hypochlorite and NaCl

    Explanation: Cold NaOH yields hypochlorite; hot NaOH is the tempting distractor which produces chlorate (NaClO3) through a different disproportionation pathway.
