In the gravimetric analysis of chloride by precipitation, a 0.4000 g impure sample of sodium chloride was treated with an excess of AgNO3, the precipitate was collected, washed to remove impurities, and dried to get a constant weight of 0.9332 g of AgCl. Express the result of the analysis in % Cl and in %NaCl (or percent purity of the sample). Reaction involved: NaCl + AgNO3 → AgCl + NaNO3 At. mass: Cl 35.45, Ag 107.87, Na 22.99 a. what is the sample used in the analysis? b. what is the mass of the sample used in the analysis? c. What is the residue or weighed form in the analysis? d. What is the mass of the residue or weighed form? e. In the calculation of the mass of CI, what is the gravimetric factor? Round off your answer to 6 sig. fig. and include the unit. f. What is the mass of Cl in the residure? to 6 sig. fig. Round off your answer
