X 34- In a given experiment, 10 ml solution of oxalic acid was prepared. A 1 ml of this solution was transferred to another 10 ml volumetric flask, and water was added to the mark. All this solution was titrated against 0.011 M NaOH. At equivalence, volume of NaOH used was 20ml. Calculate the solubility of oxalic acid in g/100ml. MW of oxalic acid =126 g/mol MW of NaOH = 40 g/mol O A. 2.772 O B. 13.86 O C. 1.386 O D. 0.1386 Correct answer C. 1.386
✓ 35. The amount of CaCO3 per antacid tablet was determined by dissolving a sample of antacid (0.145 g) in 10.00 mL HCI 0.500 M followed by back titration with 15.0 mL of standardized solution of NaOH with a concentration of 0.250 M. calculate the actual ANC in mmoles/g. Mw CaCO3 100.0869 g/mol A. 1.25 B. 8.62 O C. 4.31 O D. 10.01
