A student is asked to standardize a solution ofpotassium hydroxide. He weighs out0.965 g potassium hydrogen phthalate(KHC8H4O4, treat this as amonoprotic acid).
It requires 25.9 mL of potassiumhydroxide to reach the endpoint.
A. What is the molarity of the potassiumhydroxide solution? _________M
This potassium hydroxide solution is then used totitrate an unknown solution of hydrochloricacid.
B. If 21.5 mL of thepotassium hydroxide solution is required toneutralize 27.7 mL of hydrochloricacid, what is the molarity of the hydrochloricacidsolution? ________M
Please explain :)
