Answer:

pH of 7 (neutral)

Step-by-step explanation:

At end of titration or equivalence point (point where you have added equal molar amounts of acids and bases) , the pH is 7.0 because the solution only contains water and a salt (which is a main characteristic of acid and base titrations/reactions).

The reason we only have water and salt is because H+ from acids neutralize OH- molecules in the solution, making water (which is neutral) and the salt does not affect the pH.

Since at equivalence point nor H+ or OH- reigns supreme (that is both are at equal molarity/concentration) the pH is neutral. The pH would be acidic or basic depending on if H+ was high or low, but here H+ is equal with OH- thus pH is neutral.
