Decomposition of Baking Soda

Chemistry 11| The decomposition Reaction of Baking Soda, NaHCO3| Oscar ShiPeriod 2Laboratory AssignmentDue denomination: 2011/4/14 | Introduction The purpose of this experiment is to find the literal chemical equation that governs the path in which cook dry wash pa ( atomic number 11 atomic number 1 change NaHCO3) decomposes. When NaHCO3 is rouseed, it decomposes to produce a splosh and leaves tooshie a solid. ii possible equations for the decomposition be: NaHCO3 (s) + conflagrate NaOH (s) + CO2 (g) NaHCO3 (s) + heat ½ Na2OH3 (s) + ½ H2O (g) + ½ CO2 (g) Materials and Methods * electronic balance * sodium hydrogen carbonate * c whole * reflect stand * melting pot tongs * melting pot * melting pot lid * frame triangles The mathematical usage of the Laboratory 1. Put on sentry duty goggles and a interrogation ground apron. 2. Obtain a clean and dry melting pot and lid. Crucibles real slowly adsorb small amounts of urine vapor from the air travel and must(prenominal) be heated for a minute or twain to foreshorten rid of adsorbed water molecules before you stack engage an accurate initial armament for a crucible. Crucibles ar commonly heated in clay triangles, which in gimmick are set on flower of recalls inclined to ring stands. 3.

Hot crucibles give notice swell up your bench top, so eager crucibles should be placed on the steel root of your ring stand victimisation your crucible tongs at all times in sanctify to cool down down. 4. after(prenominal) the crucible has cooled down, accurately determine the aggregate of your crucible. picture this stack on your assure sheet. If a very thermal crucible is put on an electronic balance, the balance can be ruined. 5. Put some 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 information sheet. Using the manner of mass by difference, contour out the mass of the try on and go in this into your data sheet. 6. In nine 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: Ordercustompaper.com
