Baking soda is a very important ingredient in kitchen chemistry because when reacted with a weak acid in a cake, carbon dioxide bubbles are produced, causing the batter to rise. In this experiment, the mass of the reactants and products were measured and recorded, as well as relative masses and number of moles. These numbers will help the student to understand the mass and mole relationships. In the data table, the mass of the dish and watch glass was recorded as 50.43 grams. The mass of the dish, glass, and 2.38 g of baking soda was 52.81 grams. The mass of the dish, glass, and NaCl residue after the heating of the dish was 51.4 g. This means that after the substance was heated, a chemical reaction took place, and the product, NaCl, was 1.4 grams less than the reactant, NaHCO3. In the calculations table, the mass of the reactant, NaHCO3, was found to be 2.38 g. The number of moles of NaHCO3 reacted was .028 moles. The mass of the product NaCl was 1.41 g. The number of moles of NaCl produced was .028 mole
The balanced equation used to help figure out those numbers is:
