Final answer:
The titration of HNO₃ with NaOH is expected to have an equivalence point with a neutral pH, as it involves a strong acid reacting with a strong base to produce water and a salt, with no effect on the solution's pH.
Step-by-step explanation:
The titration expected to have an equivalence point with a neutral pH (pH = 7) is the titration of HNO₃ with NaOH. This is because the reaction involves a strong acid (HNO₃) with a strong base (NaOH). When equal moles of a strong acid and a strong base react, the products are water and a salt, neither of which affects the pH of the solution. As a result, the pH at the equivalence point will be 7, indicating a neutral solution. Other combinations, such as the titration of a weak acid with a strong base (e.g., HC₂H₃O₂ with KOH) or the titration of a weak base with a strong acid (e.g., NH₃ with H₂SO₄), will not have a neutral pH at the equivalence point because the weak acid or base does not fully dissociate, leading to a buffered solution.
