In an experiment on evaluation of antacid containing magnesium carbonate, a tablet weighing 2.50 g was completely dissolved using 5.00 mL of 1.00 M hydrochloric acid. The excess of acid was then back titrated with 1.00 M NaOH solution, with a pH indicator. The equivalence point was achieved when 2.30 mL of alkali was added. What was the content of magnesium carbonate in moles per gram? (A) 0.00031 (B) 0.0042 (C) 0.0084 (D) 0.0011 (E) None of the above. If so, what is your answer?

In a titration of 41.34 mL of 0.3483 M ammonia with 0.3483 M aqueous nitric acid, what is the pH of the solution when 41.34 mL of the acid have been added?
2.60 g of sodium acetate, CH3COONa was dissolved in 150.0 mL ofwater, H2O. A solution of 0.025 M ethanoic acid, CH3COOH was addedinto the above salt solution. Calculate the pH of the mixed solution.
During the titration of an HClO4 solution with 0.10320 M NaOH, a student, Lovely became distracted and overshot the endpoint. A fellow student Ashley suggested that he should record the present volume of NaOH added and titrate the excess with a standard acid solution. If the original sample volume was 25.000 mL, the volume of NaOH added was 28.060 mL. It took 3.4700 mL of 0.10940 M HCl to back-titrate the NaOH and calculate the molar concentration of the original HClO4
The purity of a pharmaceutical preparation of sulfanildamide (C6H4N2O2S), is prolonged oxidizing the sulfur in the sample to SO2 and bubbling this SO2 through a solution of H2O2 which converts it to H2SO4. The acid is titrated with a standard solution of NaOH (0.1251 M) until the end point with bromothymol blue, which changes color when both protons of the acid sulfuric have been neutralized. Calculate the purity of the preparation in % by weight given that a sample of 0.5136 g required 50.00 mL of the NaOH solution
If Sn3(PO4)2 solution is to be subjected to argentometric titration, a) Write the balanced titration reaction.
