Sulfur Dioxide is:

Sulfur Dioxide is:

• A. A colorless, corrosive gas directly damaging to both plants and animals
• B. A colorless, odorless gas product of complete combustion
• C. A greenish gas used in food coloring
• D. A liquid solvent for cleaning metal

Answer: (A)

Sulfur dioxide is a colorless gas that is corrosive and can directly harm living tissues. Its irritant nature means it damages both plants and animals exposed to it, harming leaf tissues and reducing plant health while irritating human and animal respiratory systems. It also has a distinct, sharp odor, so it isn’t odorless, which helps distinguish it from other gases. It is not produced only by complete combustion; it forms when sulfur-containing materials burn and is released as sulfur dioxide, not as a benign or purely inert gas. It isn’t a greenish gas, a liquid solvent, or used as a food coloring. Because of these properties, the description that best fits sulfur dioxide is a colorless, corrosive gas directly damaging to both plants and animals.
