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