The chemical formula for Sulfuric Acid is H₂SO₄. This formula indicates that each molecule of sulfuric acid is composed of two hydrogen atoms, one sulfur atom, and four oxygen atoms. Sulfuric acid is a strong mineral acid widely used in various industrial applications, including battery production, fertilizer manufacturing, and chemical synthesis. Its strong acidic properties and ability to donate protons make it an integral part of many chemical reactions in both laboratory and industrial settings.

The other options do not represent sulfuric acid. H₂S is hydrogen sulfide, a compound with different properties and uses. H₂C₆H₈O₇ refers to citric acid, which is an organic compound often found in citrus fruits. H₂O is simply water, a completely different substance. Understanding the distinct characteristics and chemical structures of these compounds is key in the study of chemistry and wastewater treatment processes.
