How to Prepare Carbon Dioxide Gas
These are instructions for preparing carbon dioxide gas (CO2) from calcium carbonate and hydrochloric acid. Carbon Dioxide Reactants Only two materials are needed to make carbon dioxide: calcium carbonate (marble chips)5M hydrochloric acid Carbon Dioxide Gas Preparation Add 5M hydrochloric acid to 5g-10g marble chips. Carbon dioxide gas is released by the chemical reaction.Collect the carbon dioxide from the upward displacement of air in a hood. Carbon dioxide is about 60% denser than air, so it will fill the reaction container. Chemical Reaction 2HCl CaCO3 → CO2 CaCl2 H2O
