(i) Fill a jar with carbon dioxide and invert it over a similar jar full of air. After a few
moments separate the jars, pour a little lime water in the lower one and shake it. The lime
water will turn milky indicating that the carbon dioxide has fallen into the lower jar because
it is the heavier gas.
(ii) Repeat the experiment with the carbon dioxide in the lower jar and invert a jar of air on
top of it. If the jars are left for about 5 minutes carbon dioxide will be carried into the
upper jar by diffusion; in the same way air will be carried into the lower jar. The lime water
test will show the presence of carbon dioxide in the upper jar.
