Commercial samples labelled ammonium carbonate no longer contain this compound, but a mixture that has similar ammonia content. Since it readily degrades to gaseous ammonia and carbon dioxide upon heating, it is used as a leavening agent and also as smelling salt.
Anhydrous sodium carbonate melts at 851Â°C (1124 K); however, it gradually decomposes in the temperature range you've specified, according to. Sodium bicarbonate is even less stable with respect to heating. Solid NaHCO 3 begins to lose carbon dioxide and water around 100Â°C, with complete conversion to sodium carbonate by 200Â°C: In aqueous solution, carbon dioxide production begins at room temperature and decomposition of NaHCO 3 (aq) is essentially complete if the solution is brought to boiling.
