  1. Question 1

    Q1. In a laboratory experiment, chlorine gas is bubbled through a cold, dilute solution of sodium hydroxide. Which two sodium salts are produced in this disproportionation reaction?

    • A) Sodium chloride and sodium chlorate(V)
    • B) Sodium chloride and sodium chlorate(I)
    • C) Sodium chlorate(I) and sodium chlorate(V)
    • D) Sodium chloride and sodium hydroxide

    Answer: Sodium chloride and sodium chlorate(I)

    Explanation: Chlorine reacts with cold, dilute NaOH to form NaCl and NaClO; NaClO3 only forms when the solution is hot and concentrated.
