Titrations: Finding Mass Percent of Arsenic in a PesticideThe arsenic in a 1.0211-g sample of a pesticide was converted to H3AsO4 by suitable treatment. The acid was then neutralized and exactly 40.00 mL of 0.05922M 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 14.76 mL of 0.1023 M KSCN; the reaction was Ag+ + SCN- yields AgSCN (solid). Calculate the percent of As in the pesticide sample. You don't need to worry about propagating error for this.
