Baking Soda Purity Lab

| Quality Control for the Athenium cook Soda Company:| A Self Directed Experiment| | Introduction Sodium hydrogen ampere-secondate or sodium hydrogen carbonate, NaHCO3, is commonly referred to and known as baking seltzer. Baking soda has many uses and applications (e.g., as a leaven agent in cooking, as an acid-base neutralizer in the laboratory, as a cleaning agent in the home and office, and in individualized hygiene and medical yields). Baking soda is mainly on the watch by the Solvay process, which is the reaction of sodium chloride, ammonia, and carbon dioxide in water system. In industrial practice, this reaction is typically carried come on by fling concentrated brine (i.e., salt water containing a last concentration of sodium chloride (NaCl)) through with(predicate) devil newspaper columns. In the firstborn tower, ammonia (NH3) bubbles up through the brine, where it is absorbed. Then, in the second tower (known as the solvay tower), carbon dioxide (CO2) bobble passes through the ammoniated brine, and sodium bicarbonate (NaHCO3) precipitates out of the solution. In a similar fashion, the Athenium Baking Soda Company (ABSC) produces baking soda by reacting liquid ammonium hydrogen carbonate with brine, as follows (Eq.

1): NH4HCO3(s) + NaCl(aq) ? NaHCO3(aq) + NH4Cl(aq)(Eq. 1) In plus to sodium chloride, brine a great deal contains potassium chloride, lithium chloride, and calcium chloride (i.e., KCl, LiCl, and CaCl2, respectively). Consequently, these compounds may be infix in (and thus contaminate) the sought after solid product i.e., baking soda (Na HCO3) when it is dried and filtered. In! come in to acquire the composition and purity of the baking soda produced by ABSC, group AMEE will utilize the following data-based techniques. First, using thermic gravimetric analysis, Team AMEE will determine the percent by mass of sodium bicarbonate in a 1.000 g sample of ABSCs baking soda-mixture. In that regard, when heated sufficiently in a...If you want to get a full essay, order it on our website: OrderEssay.net
