Potassium hydrogen phthalate is a solid, monoprotic acid frequently used in the laboratory to standardize strong base solutions. It has the unwieldy formula of KHC&H4O4. This is often written in shorthand notation as KHP. How many grams of KHP are needed to exactly neutralize 34.6 mL of a 0.549 M barium hydroxide solution ? grams KHC&H4O4

Question

*Please answer both parts.

A student is asked to standardize a solution of calcium hydroxide. He weighs out 0.934 g potassium hydrogen phthalate
(KHC3H404, treat this as a monoprotic acid).
It requires 32.5 mL of calcium hydroxide to reach the endpoint.
A. What is the molarity of the calcium hydroxide solution?
M
This calcium hydroxide solution is then used to titrate an unknown solution of hydroiodic acid.
B. If 17.3 mL of the calcium hydroxide solution is required to neutralize 16.2 mL of hydroiodic acid, what is the molarity of the
hydroiodic acid solution?
M
