The conjugate acid of HSO4– (hydrogen sulfate ion) is H2SO4 (sulfuric acid).
Here’s the explanation:
In chemistry, a conjugate acid is formed when a base gains a proton (H+). In this case, HSO4– acts as a base and accepts a proton to form its conjugate acid, H2SO4.
The reaction can be represented as:
HSO4– + H+ → H2SO4
This reaction shows that when HSO4– gains a proton, it becomes H2SO4, which is its conjugate acid.
