What is the chemical formula for sulfuric acid?

The chemical formula for sulfuric acid is accurately represented as H₂SO₄. This compound consists of two hydrogen atoms (H), one sulfur atom (S), and four oxygen atoms (O). Sulfuric acid is a strong acid and is widely used in various chemical processes, including the manufacture of fertilizers and in petroleum refining.

Understanding the components of H₂SO₄ can help contextualize its behavior in chemical reactions; the two hydrogen atoms indicate its acidic properties, while the sulfur and oxygen atoms contribute to its overall molecular structure and reactivity. The presence of multiple oxygen atoms also highlights its status as a diprotic acid, meaning it can donate two protons.

In contrast, the other chemical formulas listed do not correspond to sulfuric acid. HCl is hydrochloric acid, HNO₃ is nitric acid, and CH₃COOH is acetic acid, each with distinct properties and applications.
