Experiment for Diffusion? - correct answer 1) HCl placed at one end of the test tube, ammonia solution at the other. 2) Where they meet, a ring of Ammonium Chloride appears. 3) The diagram shows that the ammonia is closer to the ring, showing that ammonia must have travelled faster, showing it's a lighter gas. Experiment for Dilution? - correct answer 1) Put a coloured substance in a solvent e.g f...
