Answer:

the number of moles of H+ ions equals the number of moles of OH– ions

Explanation:

The equivalence point, is the point at which the acid has completely reacted with the base.

In other words, the H+ ions from the acid have completed reacted with the OH- ions from the base, and in order to complete the reaction the moles of OH- must be equal to the number of moles of H+ in the inicial solution.

This is different to the moles of acid or base, because in this case we have two moles of H+ per mol of acid (H2SO4)
