Question

Which of the following are the properties of carbon dioxide?

• A. Carbon dioxide is non-combustible.
• B. Carbon dioxide is appreciably soluble in water.
• C. Carbon dioxide is a stable compound.
• D. All of the above

Answer 1

The correct option is D

All of the above

Carbon dioxide is an odourless gas. It is one and a half times heavier than air. It is non-combustible i.e, not a supporter of combustion. Hence, it is used for extinguishing fire. It is a stable compound. Carbon dioxide is appreciably soluble in water. The solubility decreases with the rise in temperature.
