What is the chemical formula for nitric acid?

Nitric acid is a strong acid commonly used in various applications, including fertilizers, explosives, and the production of plastics. Its chemical formula is HNO3. This formula indicates that each molecule of nitric acid consists of one hydrogen atom (H), one nitrogen atom (N), and three oxygen atoms (O).

Understanding the composition within the chemical formula is crucial. The presence of nitrogen in the formula signifies its importance in reactions where nitrogen oxides may form, particularly in industrial processes. The oxygen atoms contribute to the acidic properties and the reactivity of the compound as they allow for the formation of nitrate ions when nitric acid dissociates in solution.

The other options represent different chemical compounds: HCl is hydrochloric acid, H2SO4 is sulfuric acid, and NH3 is ammonia. Each of these has distinct properties and uses that differ significantly from those of nitric acid, reinforcing the unique identity and significance of the HNO3 formula.
