The arsenic in a 1.010 g sample of a pesticide was converted to H3ASO4 by suitable treatment. The acid was then neutralized, and exactly 40.00 mL of 0.06222M AgNO3 was added to precipitate the arsenic quantitatively as Ag;AsO4. The excess Ag in the filtrate and in the washings from the precipitate was titrated with 10.76 mL of 0.1000MKSCN; the reaction was Ag* + SCN→ AgSCN(s) Calculate the percent AsO3 in the sample.
