Sodium bicarbonate (baking soda), NaHCO,, can be purified by dissolving it in
hot water (60 °C), filtering to remove insoluble impurities, cooling to 0 °C to
precipitate solid Nalco, and then filtering to remove the solid, leaving
soluble impurities in solution. Any Nauco, that remains in solution is not?
recovered. The solubility of Nauco, in hot water of 60 °C is 164 g/L. Its
solubility in cold water of 0°C is 69 g/1. What is the percent yield of NaHCO,
when it is purified by this method?
