The decomposition reaction of sodium bicarbonate or baking soda is an important chemical reaction for baking because it helps baked goods rise it's also how you can make sodium carbonate, another useful chemical, also called washing soda. By determining the enthalpy changes for the reactions between sodium carbonate and sulphuric acid, and between sodium hydrogen carbonate and sulphuric acid, it is possible to determine, indirectly, the enthalpy change for the decomposition of sodium hydrogen carbonate.
All the carbonates in this group undergo thermal decomposition to give the metal oxide and carbon dioxide gas thermal decomposition is the term given to splitting up a compound by heating it all of these carbonates are white solids, and the oxides that are produced are also white solids. Carbonates and cooking here are the equations for the thermal decomposition of sodium hydrogen carbonate: sodium hydrogen carbonate → sodium carbonate + carbon dioxide + water. Proceeding from khso4, k2s2o8, nahso4 and na2s2o8, potassium- and sodium-pyrosulfates were prepared and their thermal decomposition was investigated by a tga method.
For the case of pure na 2 co 3, the thermal decomposition started from its melting point and continued as the temperature was increased, but at a very slow rate for li 2 co 3 , however, the decomposition occurred at much faster rates than that for na 2 co 3.
