How will you test for the gas which is liberated when hydrochloric acid reacts with an active metal?

Carbon dioxide (CO2) gas is evolved during the reaction. We pass this gas through lime water which turns milky because of the CO2 passing through it. If we keep on passing the gas through the milky lime water, it would become clear again.
