70% to pass

Sulfuric acid is a _______________.

A colorless liquid with a pleasant fruity odor
B colorless-to-brown liquid with a choking odor when hot
C whitish liquid with a faint, pleasant odor
D clear syrupy liquid with no odor
AI Explanation

The correct answer is B) colorless-to-brown liquid with a choking odor when hot. Sulfuric acid is a highly corrosive and dangerous chemical. It is a colorless to dark brown oily liquid with a pungent, choking odor, especially when heated. The other answer choices do not accurately describe the physical properties of sulfuric acid. For example, it does not have a pleasant fruity odor (A), it is not whitish in color (C), and it is not a clear syrupy liquid with no odor (D). The key identifying characteristics of sulfuric acid are its corrosive nature, brownish color, and strong unpleasant odor when heated, which makes option B the correct answer.
