GRAVIMETRIC ANALYSIS OF A TWO COMPONENT MIXTURE A mixture of NaHCO 3 and Na 2 CO 3 reacts with hydrochloric acid solution to produce three common products, sodium chloride, carbon dioxide and water according to the following balanced chemical equations. NaHCO 3(s) + HCl (aq) →  NaCl (s) + CO 2(g) +  H 2 O (l) (1) Na 2 CO 3(s) + 2HCl (aq ) → 2NaCl (s) + CO 2(g) + H 2 O (l) (2) Mass of mixture (gr) = mass (gr) of NaHCO 3 + mass (gr) of Na 2 CO 3 (3) Mass of NaCl (gr) = mass (gr) of NaCl formed + mass (gr) of NaCl formed          (4) from the NaHCO 3 from the Na 2 CO 3 NOTE!!!
