360Science™: Gravimetric Analysis


Students precipitate calcium carbonate by mixing aqueous solutions of sodium carbonate and calcium chloride. They then determine the amount of calcium carbonate produced by gravimetric analysis. Students learn to set up and use a vacuum filtration or gravity filtration apparatus and how to use basic stoichiometric calculations.
