A student is asked to standardize a solution of potassium hydroxide. He weighs out 1.06 g potassium hydrogen phthalate (KHC8H4O4, treat this as a monoprotic acid).

It requires 21.6 mL 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 hydrobromic acid.

B. If 12.6 mL of the potassium hydroxide solution is required to neutralize 10.2 mL of hydrobromic acid, what is the molarity of the hydrobromic acid solution?  M
