Answer: H₂SO₄ is the chemical formula that represents sulfuric acid.
Explanation:
1) H stands for hydrogen and H₂ means that each unit contains two atoms of hydrogen.
2) S stands for sulfur. Since there is not subscript, means each unit contains one atom of sulfur.
3) O stands for oxygen, and O₄ means that each unit has four oxygen atoms.
4) The way the compound is build up is the S atom at the center with two double bonds to each to one atom of O, and two single bonds one to each OH ion.
5) Sulfuric acid is a strong acid, so it dissociates in water and alghough the formula H₂SO₄ is used to represent it, the aqueous solution is formed by ions: HSO₃⁻, H⁺, SO₄²⁻, and OH⁻, as represented by these dissociation equaitons show:
1) H₂SO₄ ⇄H⁺ + HSO₄⁻ first dissociation
2) HSO₄⁻ ⇄ H⁺ + SO₄²⁻ second dissociation
So, H₂SO₄ is one form to represent sulfuric acid.
In an aqueous solution, H₂SO₄ represents sulfuric acid.
In an aqueous solution, H₂SO₄ represents sulfuric acid. Sulfuric acid is a strong diprotic acid that ionizes in two stages. The first stage is essentially complete in an aqueous solution, while the secondary ionization is less complete, resulting in the formation of HSO₄⁻, which is a moderately strong acid.
