WebMar 15, 2024 · Strong Acid-Base Titration Curve This strong acid-strong base titration curve looks different than if one component was a weak acid or base in a few ways. First, the... Webof excess base present. The equivalence point for the titration of a strong acid with a strong base occurs when [OH–] exactly equals [H 3 O +] in the solution; pH = 7.0. The situation in the case of the titration of a weak acid with a strong base is somewhat different due to the fact that a weak acid is only partially ionized in aqueous solution.
