student is asked to standardize a solution of calcium hydroxide.He weighs out 0.993 g potassium hydrogen phthalate (KHC8H4O4, treatthis as a monoprotic acid). It requires 20.1 mL of calciumhydroxide to reach the endpoint.
A What is the molarity of the calcium hydroxide solution?
This calcium hydroxide solution is then used to titrate anunknown solution of hydroiodic acid.
B. If 25.5 mL of the calcium hydroxide solution is required toneutralize 15.0 mL of hydroiodic acid, what is the molarity of thehydroiodic acid solution? M
