Which compound does h2so4 represent when in an aqueous solution

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.

i believe the answer is 5,000
