Question 1 · 1 mark · Difficulty 1/3

What is the colour of chlorine gas at room temperature?

  1. Colourless
  2. Yellow-green
  3. Red-brown
  4. Purple
Show answer & explanation
✓ Answer: BYellow-green
Award 1 mark for identifying chlorine as a yellow-green gas. A is incorrect — chlorine has a distinct colour unlike hydrogen or oxygen. C is incorrect — red-brown describes bromine vapour. D is incorrect — purple describes iodine vapour.
Question 2 · 1 mark · Difficulty 2/3

A student added chlorine water to a solution of potassium bromide. The solution turned orange. Which statement correctly explains this observation?

  1. Bromine has displaced chlorine from solution
  2. Chlorine has oxidised bromide ions to bromine
  3. Potassium chloride has decomposed
  4. Chlorine has been reduced to chloride ions only
Show answer & explanation
✓ Answer: BChlorine has oxidised bromide ions to bromine
Award 1 mark for recognising the displacement reaction where chlorine oxidises Br⁻ to Br₂. A is incorrect — chlorine is more reactive than bromine, so bromine cannot displace chlorine. C is incorrect — potassium chloride is formed, not decomposed. D is incorrect — while chlorine is reduced, the key observation (orange colour) is due to bromine formation.
