Q:

What is the formula for nitric acid?

A:

The chemical formula for nitric acid is NHO3. The molecule has a central nitrogen atom that is bonded in a triangular formation to three oxygen atoms.

One of the oxygen atoms is single-bonded to the nitrogen atom, one is double-bonded and one is single-bonded to the nitrogen with an additional bond to a single hydrogen atom. All of the atoms are on the same plane. Nitric acid is polar, as the central nitrogen atom is positively charged, while the lone single-bonded oxygen atom is negatively charged. This makes nitric acid soluble in water. However, nitric acid also reacts with water to generate heat.
