preparation of carbon dioxide write two uses of the gas prepared ?
Answers
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.
