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

Potassium hydrogen phthalate (KHP, HC8H4O4K) is used to standardize sodium hydroxide. If 25.00 mL of NaOH (aq) is required to titrate 0.8500 g KHP to the equivalence point, what is the concentration of the NaOH(aq)? (The molar mass of KHP = 204.2 g/mol) HC8H4O4-(aq) + OH-(aq) → C8H4O42-(aq) + H2O
A chemistry student needs to standardize a fresh solution of sodium hydroxide. She carefully weighs out 316.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 93.2mL of sodium hydroxide solution. Calculate the molarity of the student's sodium hydroxide solution. Be sure your answer has the correct number of significant digits.
0.3456 g of a solid acid is dissolved in 50 mL of water in a flask and a few drops of phenolphthalein are added to the solution. A buret containing 0.2545 M NaOH is prepared with an initial volume of 10.50 mL. The acid is accidentally titrated with the base beyond the end point, so 1.52 mL of 0.187 M HCl are added to the flask. The titration with the base is continued to a final volume reading of 40.55 mL. Calculate the molar mass of the solid acid.
