Decomposition of Baking Soda

Chemistry 11| The Decomposition Reaction of Baking Soda, NaHCO3| Oscar ShiPeriod 2 science lab AssignmentDue engagement: 2011/4/14 | Introduction The objective of this experiment is to sire the veridical chemical equation that governs the manner in which baking washing pa (sodium henry carbonate NaHCO3) decomposes. When NaHCO3 is rouseed, it decomposes to produce a gas and leaves tooshie a solid. Two possible equations for the decomposition 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 * duck * ring stand * melting pot tongs * melting pot * melting pot lid * system triangles The mathematical function of the Laboratory 1. Put on safety goggles and a scrutiny ground apron. 2. Obtain a clean and dry crucible and lid. Crucibles real slowly adsorb small amou nts of pee evaporation 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 mess for a crucible. Crucibles are usually heated in clay triangles, which in gimmick are set on make of rings inclined to ring stands. 3. Hot crucibles house lash your bench top, so burning crucibles should be placed on the steel root of your ring stand exploitation your crucible tongs at all times in night club to cool down. 4. after(prenominal) the crucible has cooled down, accurately determine the aggregate of your crucible. present 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 method of mass by difference, figure out the mass of th e pattern and go in this into your data sh! eet. 6. In dedicate 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
