Decomposition of Baking Soda

Chemistry 11| The Decomposition Reaction of Baking Soda, NaHCO3| Oscar ShiPeriod 2 science lab AssignmentDue assigning: 2011/4/14 | Introduction The objective of this experiment is to rise the veridical chemical equation that governs the manner in which cook washing pa (sodium heat content carbonate NaHCO3) decomposes. When NaHCO3 is rouseed, it decomposes to produce a gas and leaves tooshie a solid. Two possible equations for the disintegration be: NaHCO3 (s) + heat NaOH (s) + carbon dioxide (g) NaHCO3 (s) + heat ½ Na2OH3 (s) + ½ H2O (g) + ½ CO2 (g) Materials and Methods * electronic balance * sodium hydrogen carbonate * spring * ring stand * melting pot tongs * melting pot * melting pot lid * dust triangles The mathematical function of the Laboratory 1. Put on safety goggles and a interrogation ground apron. 2. Obtain a clean and dry melting pot and lid. Crucibles real slowly adsorb s mall amounts of wet dehydration 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 peck for a crucible. Crucibles are usually heated in clay triangles, which in gimmick are set on gain of rings inclined to ring stands. 3.

Hot crucibles tail end pip your bench top, so naughty crucibles should be placed on the steel root of your ring stand utilize your crucible tongs at all times in rule to cool down. 4. after(prenominal) the crucible has cooled down, accurately determine the aggregate of your crucible. go in thi s mass on your date sheet. If a very hot cru! cible 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 rule of mass by difference, figure out the mass of the standard and go in this into your data sheet. 6. In rate 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
