The emission analysis will be used to determine the salts other than baking soda present. Each salt solution will burn a unique color and have a unique wavelength. Once we have those for each salt we can burn the baking soda sample and that should give us 2 or more distinct wavelengths (1 for baking soda, and 1 or more for each salt). Experimental List of Chemicals Sodium Carbornate (standard) Baking soda sample (mixture) 1.0M HCl solution .1M Calcium Chloride solution .1M Potassium Chloride solution .1M Lithium chloride solution Procedure Part 1 - Determining Mass Percentage of NaHCO3 There are two methods to determine the mass percentages of the sample. The first way is through heating to a constant mass. First, obtain a crucible and clean it by adding a few mL of HCL to it. Let it sit for about five minutes. After five minutes, dispose
of the HCl in the waste container and rinse it thoroughly with water. Then, using a ring stand and clay triangle, suspend the crucible over a bunsen burner and heat it for about 5 minutes to finish cleaning it, then let the crucible cool. Weigh the cooled crucible with about 1 g of the sample. Heat the crucible and sample gently for 5 minutes and then vigorously for 15 minutes. After the crucible cools, weigh it again. Repeat this process
