student is asked to standardize a solution of calcium hydroxide. He weighs out 0.993 g potassium hydrogen phthalate (KHC8H4O4, treat this as a monoprotic acid). It requires 20.1 mL of calcium hydroxide to reach the endpoint.

A What is the molarity of the calcium hydroxide solution?

This calcium hydroxide solution is then used to titrate an unknown solution of hydroiodic acid.

B. If 25.5 mL of the calcium hydroxide solution is required to neutralize 15.0 mL of hydroiodic acid, what is the molarity of the hydroiodic acid solution? M

A chemistry student needs to standardize a fresh solution of sodium hydroxide. She carefully weights out 305.mg of oxalic acid(H2C2O4), a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in 250.mL of distilled water. The student then titrates the oxalic acid solution with her sodium hydroxide solution. When the titration reaches the equivalence point, the student finds she has used 69.4mL of sodium hydroxide solution. Calculate the molarity of the student's sodium hydroxide solution. Be...
