Chemistry

The concentration of barium ions in any solution can also be determined via gravimetric analysis. An impure sample of barium nitrate with a mass of 1.234 g, is completely dissolved in water and the resulting solution is reacted with an excess of aqueous sodium sulfate. A precipitate forms, and after filtering and drying, it was found to have a mass of 0.848 g.

A) What is the relevance of adding eccess sodium sulfate?

B) Calculate the % of barium nitrate in the original 1.234 g sample.
