Question

In the gravimetric determination of sulfate in a 0.5613 g sample of pure NazSO4, a BaSO. precipitate weighing 0.4309 g was obtained. The weight of the precipitate was smaller than the theoretical one. since some BaSO& was converted to Bas during the heating process. (a) Calculate the percent of Bas in the precipitate (Hint: best to solve algebraically) (b) Calculate the percent error of the analysis (Hint: compare calculated with weight stated in problem).
