Sulfuric acid, H2SO4, is a polyprotic acid. More specifically, it is a diprotic acid, meaning that it has the capacity to donate two protons. Write out the two chemical equations for this acid acting as a proton donor in water.

The answer to your question is below

Explanation:

Data

sulfuric acid = H₂SO₄

Proton donors give hydrogens to other molecules most of the time bases or alkalis.

When a molecule donates hydrogen it acquires a negative charge.

First dissociation reaction

                H₂SO₄   +  H₂O  ⇒  HSO₄⁻ + H₃O⁺

Second dissociation reaction

                HSO₄⁻¹ + H₂O ⇒  SO₄⁻²  +  H₃O⁺
