How to prepare carbon dioxide in the laboratory?
Let us learn how to prepare carbon dioxide in the laboratory. Put some marble chips (calcium carbonate) in a round bottle flask fitted with a thistle funnel and a delivery tube. Place a collecting jar at the other end of the delivery tube. Pour dilute hydrochloric acid in the bottle through the thistle funnel so that the marble chips are covered with the acid. Effervescence takes place in the bottle flask and the gas is collected by upward displacement of air at the other end of collecting jar. Observe and test the properties of the gas formed. It is colourless. It has a faint odour. It is heavier than air. Put a lighted splinter in a jar containing carbon dioxide gas, it extinguishes. The gas does not support combustion. Hence we conclude that the gas given off is carbon dioxide. The equation for the laboratory preparation of carbon dioxide CaCO3(s) + 2HCl(aq) = CaCl2(aq) + H2O(l) + CO2(g)
