CARBON DIOXIDE WAS discovered over 250 years ago by the 24-year old Englishman Joseph Black. He prepared and characterized samples of CO2(g) which he called fixed air. He found that the gas could be produced by heating chalk which lost mass during the heating process. We now know this reaction is:
CaCO3(s) CaO(s) + CO2(g)
Carbon dioxide is a colorless gas present in our atmosphere at very low levels. The level of CO2 have been rising throughout the 20th century which is believed to cause the greenhouse effect by which the earth's atmosphere is slowly warming up. Carbon dioxide is essentially odorless, however it causes a sharp sensation in one's nose when inhaled — such as from the bubbles of a carbonated beverage.
