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 37.5 mL of a sodium hydroxide solution are needed to neutralize 2.14 grams of KHP, what is the molarity of the sodium hydroxide solution? __________M Oxalic acid dihydrate is a solid, diprotic acid that can be used in the laboratory as a primary standard.

a) Write the reaction for the neutralization oxalic acid (H2C2O4) with sodium hydroxide (NaOH). Note oxalic acid is diprotic (like sulfuric acid). b) A 0.1187 g sample of an unknown, diprotic solid acid is dissolved in water. 26.36 mL of 0.1000 M sodium hydroxide is used to reach the equivalence point. How many moles of sodium hydroxide were reacted? How many moles of acid reacted? What is the molecular weight of the acid?

5. The Ka and Molar Mass of a Monoprotic Weak Acid a. Suppose that–unknown to you–the primary standard KHP (potassium hydrogen phthalate, KHC8H4O4) had a potassium iodide impurity of approximately one percent by mass. How would this have influenced the calculated molarity of your sodium hydroxide solution? Would your calculated value be too low, too high, or unchanged? Explain your answer. b. Sketch a typical titration curve for a monoprotic weak acid titrated with a strong base. Label the axes...
