Question

What are the commercial uses of $C{O}_2$?

• A. To provide a "bite" in soft drinks.
• B. As fire extinguisher.
• C. As refrigerant.
• D. All of the above.

Answer 1

The correct option is D All of the above.

$C{o}_2$ adds soft drinks a pleasantly acidic flavour and an interesting mouth-feel.

carbon dioxide gas is involved in the production of refrigeration systems, welding systems, water treatment processes (to stabilize the pH of water) and carbonated beverages. It is also used in the metals industry to enhance the hardness of casting molds and as a soldering agent.

Carbon dioxide is found in various fire extinguishers and prevents oxygen from further fueling a fire. Carbon dioxide-based fire extinguishers effectively manage electrical fires and those caused by solvents, fuels and oils.

Hence, option D is correct.
