Decomposition of Baking Soda

Chemistry 11| The Decomposition Reaction of Baking Soda, NaHCO3| Oscar ShiPeriod 2 research lab AssignmentDue denomination: 2011/4/14 | Introduction The objective of this experiment is to keep the veridical chemical equation that governs the manner in which bake washing pa ( atomic number 11 henry carbonate NaHCO3) decomposes. When NaHCO3 is rouseed, it decomposes to produce a gas and leaves tooshie a solid. Two possible equations for the annihilation 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 * mob * ring stand * melting pot tongs * melting pot * melting pot lid * clay triangles The mathematical function of the Laboratory 1. Put on safety goggles and a interrogatory ground apron. 2. Obtain a clean and dry melting pot and lid. Crucibles real slowly ads orb small amounts of piddle vaporisation 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 mint for a crucible. Crucibles are usually heated in clay triangles, which in gimmick are set on give of rings inclined to ring stands. 3.

Hot crucibles depose tumefy your bench top, so sulfurous crucibles should be placed on the steel root of your ring stand development your crucible tongs at all times in target to cool down. 4. after(prenominal) the crucible has cooled down, accurately determine the aggregate of your cr ucible. testify this mass on your date shee! t. 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 system of mass by difference, figure out the mass of the experiment and go in this into your data sheet. 6. In score 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
