The arsenic in a 1.233-g sample of a pesticide was converted to H3AsO4 by suitable treatment. The acid was then neutralized, and 41.00 mL of 0.05819 M AgNO3 was added to precipitate the arsenic quantitatively as Ag3AsO4. The excess Ag+ in the filtrate and in the washings from the precipitate was titrated with 9.89 mL of 0.1000 M KSCN, and the reaction was Ag+ + SCN- ---> AgSCN (s)

Find the percentage of As2O3 in the sample.

The percentage of arsenic in a sample can be determined by titration with iodine. In the determination, all of the arsenic (As) in the sample is converted to HAsO2 followed by titration with iodine (I2) solution. The chemical equation for the reaction between HAsO2 and I2 is: HAsO2 (aq) + I2 (aq) + 2 H2O (l) → H3AsO4 (aq) + 2 H+ (aq) + 2 I − (aq) In an actual analysis, a 0.7034 g sample is dissolved and the...
