Decomposition of Sodium Bicarbonate, NaHCO 3 , Stoichiometry Lab The purpose of this lab is to: Perform a decomposition reaction and measure the mass of the product formed Part 2: Decomposition of Unknown Sodium Bicarbonate – Sodium Chloride Mixture 1) Weigh out 50-60 g of unknown mixture by difference into a heat safe container. Take out tools (tongs and striker). 2) Weigh out a second 50-60 g sample of sodium bicarbonate by difference. You will calculate the % yield to check the validity of the experimental procedure being used for thermal decomposition. Make sure that the mass is less than 165 g. 2. In this particular lab we used stoichiometry, the part of chemistry that studies amounts of substances that are involved in reactions, to observe the reactions made by combining sodium hydrogen carbonate, NaHCO3, (baking soda) and acetic acid, CH3COOH, (vinegar) together. Measure three grams of sodium bicarbonate using the scale. Purpose. Background: Sodium bicarbonate (baking soda, properly known as sodium hydrogen carbonate) is used in the preparation of many foods. Sodium bicarbonate has a steady rate of decomposition; however, by introducing heat, the energy required to break the bonds is met. sodium bicarbonate → sodium carbonate + carbon dioxide + water The balanced chemical equation appears as follows.
