Give a chemical test to distinguish between SO2 and Cl2.

On passing Sulphur dioxide gas through lime water, it turns lime water milky. Ca(OH) 2 + SO 2 CaSO 3 ↓ [white ppt.] + H 2 O Chlorine gas does not turn lime water milky. It turns moist starch iodide paper blue black. Cl 2 + 2KI 2KCl + I 2 Starch + I 2 Blue black colour

Answer

On passing Sulphur dioxide gas through lime water, it turns lime water milky.
Ca(OH)₂ + SO₂ ⟶ CaSO₃ ↓ [white ppt.] + H₂O
Chlorine gas does not turn lime water milky. It turns moist starch iodide paper blue black.
Cl₂ + 2KI ⟶ 2KCl + I₂
Starch + I₂ ⟶ Blue black colour
