30. A sample of vinegar weighing 10.52 g is titrated with NaOH. The end point is overstepped, and the solution is titrated back with HCl. From the following data, calculate the acidity of the vinegar in terms of percentage of acetic acid, CH;COOH (60.05 g/mol) Standardization Data: 1.050 mL HCI = 1.000 mL NaOH 1.000 mL NaOH = 0.06050 g benzoic acid, CHSCOOH (122.12 g/mol) Sample Analysis Data: Volume NaOH used = 19.03 ml Volume HCI used for back titration = 1.50 ml
