If barium ion is being determined by sulfate precipitation, several metal ions must be absent since they also form insoluble sulfates. Webanalysis. You will accomplish this by precipitating all of the sulfate ion present in your sulfuric acid by adding excess solid barium nitrate to your acid. You will then collect and weigh the BaSO 4 precipitate formed. By using mole ratios from the balanced equation you will determine the moles of SO 4
