Web1) The NaOH solution, which is used during the titrations, is to be standardized with a standard solution of oxalic acid: 2 OH- + (COOH) 2 → 2 H 2 O + (COO-) 2 (2) 2) During the titrations with NaOH, the total amount of acid is determined (acetic acid as well as HCl, the catalyst). Therefore it is necessary to evaluate the amount of Web35.23 mL NaOH × 0.250 mmol NaOH mL NaOH × 1 mmol HCl 1 mmol NaOH 50.00 mL solution = 0.176 M HCl Check Your Learning A 20.00-mL sample of aqueous oxalic acid, H 2 C 2 O 4, was titrated with a 0.09113- M solution of potassium permanganate, KMnO 4 (see net ionic equation below).
