Chemistry

A student is asked to standardize a solution of bariumhydroxide. He weighs out 0.989 g potassium hydrogen phthalate(KHC8H4O4, treat this as a monoprotic acid). It requires 25.0 mL ofbarium hydroxide to reach the endpoint.

A. What is the molarity of the barium hydroxide solution?

This barium hydroxide solution is then used to titrate anunknown solution of hydroiodic acid.

B. If 18.0 mL of the barium hydroxide solution is required toneutralize 23.6 mL of hydroiodic acid, what is the molarity of thehydroiodic acid solution?
