Athenium Baking Soda

umQuality Control for the Athenium baking hot hot Soda go by ships high society November 4, 2009 2 INTRODUCTION cook pappa, overly know as sodium hydrogen atomic number 6ate, NaHCO3, is a leafy ve vexable compound that we not only meeting everyday, but is profitable in many aspects of life. Its uses convert 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 answer 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 pattern the desired, fast product, there is a possibility that the presence of the last mentioned lead compounds may be found. In order to visualise quality control for the Athenium Baking Soda Companys product, we exit select three methods of experimentation to localise the virtue of its baking soda, as puff up as its composition. The graduation exercise experimental procedure to take displace lead 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 rush 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) + carbon dioxide(g) + H2O(g) by and by a ! reheating of the crucible to ensure accuracy, the stoichiometric ratio for the throng loss of CO2 and H2O per gram of NaHCO3 will be determined, along with the intact 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 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
