pH=7
This is because of the titration of strong acid with strong base at equivalence point.HNO3 is a strong acid which when reacts with KOH which is a strong base then salt and water are formed.The solution will thus become neutral.

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...
