KHC8H4O4 (KHP) is a monoprotic acid commonly used to standardize aqueous solutions of strong bases. A sample of 354.5 mg of KHP is added to water, which is then neutralized by 17.20 mL of a solution of NaOH(aq). The NaOH(aq) solution is then titrated against 0.1038 g of an unknown monoprotic acid dissolved in water to a final volume of 50.00 mL. It takes 17.56 mL of the above NaOH(aq) solution to titrate the unknown acid solution to its end point. At the end point the solution pH is 8.42. a) Calculate the concentration of the NaOH solution b) Determine the molecular mass of the unknown monoprotic acid c) Calculate the K. of the unknown monoprotic acid
