A student is asked to standardize a solution of potassium hydroxide. He weighs out 1.06g potassium hydrogen phthalate (KHC8H4O4, treat this as a monoprotic acid). It requires 17.9mL of potassium hydroxide to reach the endpoint. A. What is the molarity of the potassium hydroxide solution? M This potassium hydroxide solution is then used to titrate an unknown solution of perchloric acid. B. If 24.6 mL of the potassium hydroxide solution is required to neutralize 14.7mL of perchloric acid, what is the molarity of the perchloric acid solution? M
