Decomposition of Baking Soda

Chemistry 11| The Decomposition Reaction of Baking Soda, NaHCO3| Oscar ShiPeriod 2 science laboratory AssignmentDue appellation: 2011/4/14 | Introduction The objective of this experiment is to stripping the veridical chemical equation that governs the manner in which bake washing pa (sodium hydrogen carbonate NaHCO3) decomposes. When NaHCO3 is rouseed, it decomposes to produce a gas and leaves tooshie a solid. Two possible equations for the decomposition reaction be: NaHCO3 (s) + heat NaOH (s) + carbonic acid gas (g) NaHCO3 (s) + heat ½ Na2OH3 (s) + ½ H2O (g) + ½ CO2 (g) Materials and Methods * electronic balance * sodium hydrogen carbonate * battalion * ring stand * melting pot tongs * melting pot * crucible lid * ashes triangles The mathematical function of the Laboratory 1. Put on safety goggles and a test ground apron. 2. Obtain a clean and dry crucible and lid. Crucibles real slow ly adsorb small amounts of peeing desiccation from the air travel and must be heated for a minute or two to get rid of adsorbed water molecules before you stack get an accurate initial muckle for a crucible. Crucibles are usually heated in clay triangles, which in gimmick are set on slide by of rings inclined to ring stands. 3.

Hot crucibles give the gate lather your bench top, so bake hot crucibles should be placed on the steel root of your ring stand development your crucible tongs at all times in hostel to cool down. 4. after(prenominal) the crucible has cooled down, accurately determine the ag gregate of your crucible. figure this mass ! on your date sheet. If a very hot crucible is put on an electronic balance, the balance can be ruined. 5. Put about 5.00 g of sodium hydrogen carbonate in the cool crucible. Once again using the electronic balance, record the mass of the crucible plus baking soda accurately on your data sheet. Using the manner of mass by difference, figure out the mass of the attempt and go in this into your data sheet. 6. In position to decompose, sodium hydrogen carbonate must be heated until the crucible starts to glow an...If you expect to get a full essay, order it on our website: BestEssayCheap.com
