Athenium Baking Soda

umQuality Control for the Athenium baking hot hot Soda come about ships social club November 4, 2009 2 INTRODUCTION cook popping, overly know as sodium hydrogen atomic number 6ate, NaHCO3, is a leafy ve directable compound that we not only understand everyday, but is profitable in many aspects of life. Its uses divert 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, lithium chloride, and calcium chloride. Thus, when the aqueous baking soda is dried to contrive the desired, stiff product, there is a possibility that the presence of the latter(prenominal) lead compounds may be found. In order to crack quality control for the Athenium Baking Soda Co mpanys product, we exit select three methods of experimentation to look on the integrity of its baking soda, as puff up as its composition. The beginning experimental procedure to take displace result 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 mussiness 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 equation: 2NaHCO3(s) ? Na2CO3(s) + carbonic acid gas(g) + H2O(g) by and by a reheating of the crucible to ensure accuracy, the stoichiometric ratio for the sess loss of CO2 and H2O per gram of NaHCO3 will be determined, along with the number mass of CO2 and H2O disoriented upon heating. These will be use in order to determine 3 the mass of NaHCO3 present in the sample. Finally, using the c ollected 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
