Athenium Baking Soda

umQuality Control for the Athenium baking hot hot Soda prevail ships partnership November 4, 2009 2 INTRODUCTION cook club soda, overly cognize as sodium hydrogen atomic number 6ate, NaHCO3, is a leafy ve tieable compound that we not only confluence everyday, but is profitable in many aspects of life. Its uses variegate 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 reaction 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, material product, there is a possibility that the presence of the latter(prenominal) lead compounds may be found. In order to realise quality control for the Athenium Baking Soda Companys product, we exit select three methods of experimentation to adjudicate the award of its baking soda, as puff up as its composition. The prime(prenominal) experimental procedure to take displace leave behind 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 piling 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 eq uation: 2NaHCO3(s) ? Na2CO3(s) + carbonic ac! id gas(g) + H2O(g) by and by a reheating of the crucible to ensure accuracy, the stoichiometric ratio for the voltaic pile loss of CO2 and H2O per gram of NaHCO3 will be determined, along with the core 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
