A student weighs a sample of potassium hydrogen phthalate (KHP) to prepare a primary standard for a titration. She later discovers that the KHP was contaminated with sugar. To determine the amount of KHP in the mixture, she takes 5.942 g of the mixture and make a 100.0 mL solution. The student then titrates 10.00 mL of this solution with a 0.1491 M sodium hydroxide solution. She finds that 13.12 mL of the NaOH solution is needed to reach the...

4) Potassium hydrogen phthalate (KHP) is the primary standard for evaluating the concentration of potassium hydroxide (KOH) solutions in terms of moles per Liter. In the course of a typical titration, one mole of KHP neutralizes one mole of KOH. 1.000 grams of KHP (molar mass = 204.2 grams per mole) consumed 43.3 mL of a given KOH (potassium hydroxide) solution. What is the molarity of the KOH solution? (5 points)

Potassium hydrogen phthalate is a solid, monoprotic acid frequently used in the laboratory as a primary standard. It has the unwieldy formula of KHC8H4O4. This is often written in shorthand notation as KHP. If 31.1 mL of a barium hydroxide solution are needed to neutralize 2.41 grams of KHP, what is the molarity of the barium hydroxide solution?
