Quality Control for the Athenium Baking Soda Company 1225-022 1/30/2015 Introduction The Athenium Baking Soda Company has implemented a quality control program to check the purity and quality of their product. The Athenium Baking Soda Company has chosen from one of several methods of producing baking soda to react crystalline ammonium hydrogen carbonate with brine. NH_4 HCO_(3(s))+Na〖Cl〗_((aq)) □(→┬ ) NaHCO_(3(aq))+NH_4 〖Cl〗_((aq)) Brine is salt water containing a high concentration of sodium chloride, as well as contaminates potassium chloride, lithium chloride, and calcium chloride. Most manufacturing companies employ quality control scientists and technicians to analyze their products for purity, quality of workmanship, structural flaws, composition, and longevity. However, what is the best way to perform these quality control test and what two tests can be performed that will determine the concentration of baking soda is in the solution and what contaminates are in the solution? Quality control consist of periodic inspections designed to maintain quality during the manufacturing process. A quality control test can determine what type of contaminates are in the baking soda. Depending on the results of the quality control test the manufacturing process may be influenced for future batches. In this experiment we will determine the percent composition of the NaHCO_3 and the contaminates in the solution. Experiment 1 – Titration of NaHCO_3 with HCl. Titration allows for the equilibration of the unknown substance with an acid. The amount of acid required to neutralize the unknown will give data on the amount of base present. The titration between NaHCO_3 and HCl will determine the percent composition of NaHCO_3 in the Athenium Baking Soda. The experiment will be run at least twice and the value
