Question

What are the commercial uses of ${\text{C}}{{\text{O}}_{\text{2}}}$ ?
A.To provide a “bite” in soft drinks
B.As fire extinguisher
B.As refrigerant
D.All of the above

Answer 1

A covalently bonded chemical compound composed of two oxygen atoms and a carbon atom is termed as carbon dioxide (${\text{C}}{{\text{O}}_{\text{2}}}$). It has various uses, from industrial uses to commercial uses. It is an acidic colourless gas.

Complete step by step answer:
Carbon dioxide or we can say ${\text{C}}{{\text{O}}_{\text{2}}}$ is a covalently bonded chemical compound. As we can see in its chemical formula that it consists of two oxygen atoms and a carbon atom which are covalently bonded with each other. It is an important part of our life as it is exhaled by humans and animals and inhaled by plants to produce oxygen. Carbon dioxide is basically a colourless gas with density higher than that of dry air. Carbon dioxide comes under the category of green house gases present in the earth’s atmosphere.
It has various industrial and commercial uses, ${\text{C}}{{\text{O}}_{\text{2}}}$ is used in water treatment processes and also used in beverages to decrease its pH range, because carbon dioxide is acidic in nature. Carbon dioxide is used as fire extinguishers in homes, industries, schools and various places. It breaks the contact between the oxygen and the flames by spreading like a blanket to put off the fire. It is not conductive in nature so it can also be used to extinguish the electrical fires, and fires generated by the fuels and oils. Carbon dioxide is also known as dry ice and used as refrigerant.
Hence from the above discussions we can conclude that the commercial uses of carbon dioxide are to provide a bite in soft drinks, as fire extinguishers and as refrigerant.

So, option (D) is correct.

Note: Carbon dioxide (${\text{C}}{{\text{O}}_{\text{2}}}$) gas is soluble in water and at equilibrium the carbon dioxide with water forms carbonic acid (${{\text{H}}_{\text{2}}}{\text{C}}{{\text{O}}_3}$). The reaction involved at equilibrium is as follows:${\text{C}}{{\text{O}}_{\text{2}}} + {{\text{H}}_{\text{2}}}{\text{O}} \to {{\text{H}}_{\text{2}}}{\text{C}}{{\text{O}}_{\text{3}}}$
