What is the theoretical point when the number of moles of added is equal to the number of moles of titrated in an initial solution?

This is called the $\text{stoichiometric end point.}$

Explanation:

And of course, the end point may NOT represent a 1:1 equivalence of moles of reactant, and moles of product.

Titration of diacids represent a different stoichiometry, as shown below. As with all these types of reactions, a balanced chemical equation is necessary to represent the equivalence, the stoichiometry:

${H}_{2} S {O}_{4} \left(a q\right) + 2 N a O H \left(a q\right) \rightarrow N {a}_{2} S {O}_{4} \left(a q\right) + 2 {H}_{2} O \left(l\right)$

Most of the time, we rely on suitable $\text{indicators}$ to indicate the end point.
