Purpose: The purpose of this experiment is to determine the quantities of the impurities of the baking soda produced by the Athenium Baking Soda Company and also identify the salts present in the baking soda sample. Introduction: NaHCO3, sodium bicarbonate or even sodium hydrogen carbonate, are many different names for a common item, baking soda. Baking soda are has many different uses, most of them involving cleaning household items. It does have other uses such as a hygiene product. There are several different ways to create baking soda, but the Athenium Baking Soda Company chose to make baking soda by reacting ammonium hydrogen carbonate with a highly concentrated aqueous solution of NaCl or brine. An equation to demonstrate this process is: NH4HCO3(S) + NaCl (aq) → NaHCO3 (aq) +NH4Cl(aq) This salt-water concentration not only contains a high concentration of sodium chloride, but also concentrations of calcium chloride, potassium chloride, and lithium chloride. Because of this fact residue of NH4HCO3 will possibly contain CaCl2, KCl, and LiCl. These contaminants of the brine will provide flaws to the baking soda, and thus production must be checked often by chemists who analyze the baking soda for lifespan, composition, purity, and quality. There are a couple different ways to determine the percent composition of baking soda. The most common ways to find this percent composition are through titrations and thermal gravimetric analysis. When and if the NaHCO3 sample is found to be pure, these chemists must have a way to determine which salts are present. The best way to determine what the sample contains is by emission analysis. The first way to find the percent sample of baking soda is titration. The percent of mass or percent composition is the amount of mass in grams of NHCO3 divided by every one hundred grams of baking soda sample. The first step is
