Experiment 13 POTENTIOMETRIC TITRATION OF ACID-BASE

WebNote: You will need 500 mL minus the calculated volume of NaOH. Standardization of 0.1 M NaOH. Expand. After you have prepared 0.1 M NaOH, determine its exact concentration, or standardize it, using the acid-base titration method. In this technique, a base like NaOH is slowly added to an acid like potassium hydrogen phthalate (KHP). WebThe titration of a mixture of phosphoric acid and hydrochloric acid is complicated by the fact that phosphoric acid is a triprotic acid with K a1 = 7.5x10-3, K a2 = 6.2x10-8, and K a3 = … WebNov 13, 2024 · The objective of an acid-base titration is to determine C a, the nominal concentration of acid in the solution.
