When HNO3 (flask) is titrated with KOH (burette), which response best describes the equivalence point? O The pH = 7 since it has the same moles of acid and base present. The pH > 7 since the conjugate base would be present. The pH <7 since the conjugate acid would be present. The pH > 7 since there is a strong base present. The pH <7 since there is a strong acid present.
