Athenium Baking Soda

umQuality Control for the Athenium baking hot hot Soda backup ships order November 4, 2009 2 INTRODUCTION cook tonic, overly cognize as sodium hydrogen atomic number 6ate, NaHCO3, is a leafy ve popable compound that we not only opposition everyday, but is profitable in many aspects of life. Its uses transfer from acting as a fruit cleaning or even as a fire extinguishing. In producing it, the Athenium baking Soda Company decided to utilize the following response of ammonium hydrogen carbonate and a brine, sodium chloride: NH4HCO3(s) + NaCl(aq) ? NaHCO3(aq) + NH4Cl The brine, though mostly consisting of sodium chloride, also contains trace amounts of potassium chloride, atomic number 3 chloride, and calcium chloride. Thus, when the aqueous baking soda is dried to radiation pattern the desired, unassailable product, there is a possibility that the presence of the last mentioned lead compounds may be found. In order to experience quality control for the Atheniu m Baking Soda Companys product, we exit select three methods of experimentation to forge the ingenuousness of its baking soda, as puff up as its composition. The starting time experimental procedure to take displace give be a thermal gravimetric analysis, which will help determine the per centum composition of sodium bicarbonate of a smack of the companys baking soda.

In this experiment, a known flowerpot of a sample of the companys baking soda will be added to a crucible and heated until it decomposes into solid sodium carbonate, gaseous carbon dioxide, and gaseous water, as shown in the following equati on: 2NaHCO3(s) ? Na2CO3(s) + carbonic acid g! as(g) + H2O(g) by and by a reheating of the crucible to ensure accuracy, the stoichiometric ratio for the loudness loss of CO2 and H2O per gram of NaHCO3 will be determined, along with the full mass of CO2 and H2O disoriented upon heating. These will be utilize in order to determine 3 the mass of NaHCO3 present in the sample. Finally, using the collected data, the percent by mass of NaHCO3 in the companys sample will be calculated so that it may be used as an indicator of whether or not former(a) contaminants...If you want to get a full essay, order it on our website: OrderCustomPaper.com
