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...

During the calculations for titration of vinegar experiment, you determined the molar mass of KHP by using the mass of K, H, and P instead of using KHC8H4O4. How would this change your results? Explain. We had to find the mass of KHP, moles of KHP, moles of NaOh, and moles of acetic acid, molarity of vinegar titrated, mass of acetic acid titrated in grams, and w/v % of acetic acid in vinegar
