QUESTION 4 Sоdium hydrоgencаrbоnаte, NаHCO3, is used in the manufacture of some toothpastes and as a raising agent in food production. The purity of this substance can be obtained by measuring how much carbon dioxide is given off. 4.1 Balance the following equation which represents the thermal decomposition of sodium hydrogen carbonate. NaHCO3 (s) ¾® Na2CO3 (s) + H2O(g) + CO2 (g) (1) 4.2 If 84 grams of a sample containing sodium hydrogencarbonate was thermally decomposed and 11.5 dm3 of carbon dioxide gas was collected at room temperature and pressure (rtp). Determine the percentage purity of the sample. (Ar: Na = 23; C = 12; O = 16; H = 1) (6)
