A student is asked to standardize a solution of sodium hydroxide. He weighs out 1.09 g potassium hydrogen phthalate (KHC8H404, treat this as a monoprotic acid). It requires 33.5 mL of sodium hydroxide to reach the endpoint. A. What is the molarity of the sodium hydroxide solution? M This sodium hydroxide solution is then used to titrate an unknown solution of nitric acid. B. If 18.7 mL of the sodium hydroxide solution is required to neutralize 10.3 mL of nitric acid, what is the molarity of the nitric acid solution? M
