In a laboratory demonstration, the following reactivity tests between halogens and halide salt solutions are observed: Test Tube A: Chlorine gas is bubbled into NaBr solution → Brown color of Br2 appears. Test Tube B: Bromine water is added to NaI solution → Violet color of I2 is seen in organic layer. Test Tube C: Iodine solution is added to NaCl solution → No visible reaction occurs. Which conclusion is correctly drawn from these observations?

Share:
- 1Chlorine displaces bromine from NaBr because chlorine is more reactive than bromine✓
- 2Bromine cannot displace iodine from NaI due to its lower reactivity than iodine
- 3Iodine displaces chlorine from NaCl as iodine is more electronegative than chlorine
- 4Bromine gas can displace chlorine from NaCl solution
Correct answer
Chlorine displaces bromine from NaBr because chlorine is more reactive than bromine
