At elevated temperatures, NaHCO3 is converted quantitatively to NazCO3: 2 NaHCO:(s) → NazCO3 (s) + CO2 (g) + H20 (g). Ignition of a 0.6239-g sample of an antacid tablet containing NaHCO3 and nonvolatile impurities yielded a residue weighing 0.4129 g. Calculate the percent purity of the antacid sample. Some helpful FW: NaHCO3 = 84.01 ; Na2C03 = 105.99 ; CO2 = 44.01 ; H2O = 18.02
