How do you name HNO3?
- A.
Hydronitric acid
- B.
Nitric acid
- C.
Nitrous acid
Correct Answer
B. Nitric acidExplanation
The correct answer is Nitric acid because HNO3 is the chemical formula for nitric acid. The prefix "nitro-" indicates the presence of the nitrate ion (NO3-) in the compound, and the suffix "-ic" indicates that the compound is an acid. Therefore, HNO3 is named as nitric acid.Rate this question:
