Carbon dioxide can be obtained very simply from carbonates (e.g. marble) by dripping acid onto them. The properties of the gas obtained in this way can then be investigated with little difficulty. The student experiment described here demonstrates, among other things, two of the most important properties of carbon dioxide: the density of the gas is greater than that of air and it can extinguish flames.
