Final Answer:
When chlorine is passed into a solution of sulfur(IV) oxide in water, it forms chlorosulfonic acid (HSO3Cl) and hydrochloric acid (HCl).
Step-by-step explanation:
Chlorine reacts with sulfur(IV) oxide in water to produce chlorosulfonic acid and hydrochloric acid. The balanced chemical equation for the reaction is:
SO2 (g) + 2Cl2 (g) + 2H2O (l) -> HSO3Cl (aq) + 2HCl (aq)
To identify the products:
Chlorosulfonic Acid (HSO3Cl): It is a colorless liquid and can be identified by its characteristic acidic properties.
Hydrochloric Acid (HCl): It is a strong acid, identified by its ability to turn blue litmus paper red and evolve gas when reacted with a metal.
Confirmation tests, such as pH indicators and chemical tests for chloride ions, can be employed to identify the specific products formed.
