This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.
Asolubility of calcium hydroxide: higher, solubility of barium hydroxide: lower, thermal stability of calcium carbonate: higher, thermal stability of barium carbonate: lower
Bsolubility of calcium hydroxide: higher, solubility of barium hydroxide: lower, thermal stability of calcium carbonate: lower, thermal stability of barium carbonate: higher
Csolubility of calcium hydroxide: lower, solubility of barium hydroxide: higher, thermal stability of calcium carbonate: higher, thermal stability of barium carbonate: lower
Dsolubility of calcium hydroxide: lower, solubility of barium hydroxide: higher, thermal stability of calcium carbonate: lower, thermal stability of barium carbonate: higher
✓ Correct answer
D: solubility of calcium hydroxide: lower, solubility of barium hydroxide: higher, thermal stability of calcium carbonate: lower, thermal stability of barium carbonate: higher
