Add ≈ 30 g of baking soda (NaHCO 3) to the dish. Set up equipment as shown. Introduction. Decomposition Of Sodium Bicarbonate. The thermal decomposition of sodium bicarbonate will occur rapidly at 200 0C, but the solid product of the decomposition reaction will begin to decompose at temperatures over 850 0C. Perform all burning and heating in the fume hood. In this lab, you will decompose baking soda (sodium hydrogen carbonate or sodium bicarbonate) and use the mass relationships to determine how baking soda decomposes. Safety for this lab: Wear safety glasses at all times. This will help determine what quantity goes in the mix. states that a compound is always made up of the exact same proportion of elements by mass. The balanced equation for the decomposition of sodium bicarbonate into sodium carbonate, carbon dioxide, and water is: 2 NaHCO3 (s) → Na2CO3 (s) + CO2 (g) + H2O (g) Like most chemical reactions, the rate of the reaction depends on temperature. Keep the introduction and the purpose separate. ALWAYS clean up your entire station and any spills made at shared stations. Record the mass of a clean, dry oven-safe dish. states that mass is conserved during a chemical reaction. The two possible equations were: 2 N a H C O ⟶ N a X 2 C O X 3 + C O X 2 + H X 2 O Your company wants you to determine the correct decomposition reaction that baking soda undergoes. 2 NaHCO 3 (s) Na 2 It can also be seen from the first graph that the trend is first increased and then becomes constant at a particular time. 3) undergoes a decomposition reaction when heated to temperatures in excess of 70° C. For the purposes of this experiment, we were given that the reaction … The lab procedure that my class used can be found in the photo attachment. Using stoichiometry I calculated the mass of the product produced to be 1.276 g of sodium carbonate. Baking soda is commonly used in baking to provide a “rise” to baked goods. Before class starts: Read the lab for the week carefully before you start writing your pre-lab. Lab 27. Stoichiometry is the study of mass relationships in chemistry. 3-4 hours. The . PROCEDURE – YOU WILL WORK ON THIS LAB INDEPENDENTLY (NO LAB PARTNERS). You are graded on how you format the lab and record your data, not just data collection. Its the thermal decomposition of sodium bicarbonate, the product being sodium carbonate, carbon dioxide and water. Purpose. Sodium bicarbonate (s) →sodium carbonate (s) + carbon dioxide (g) + water (g) ___________________________________________________________________________ 2. Sodium hydrogen carbonate (also known as sodium bicarbonate or bicarbonate of soda) has the chemical formula NaHCO3. In part–A, you will analyze ‘pure sodium hydrogen carbonate (NaHCO3)’. By2³$ŠÅ-êÿ¬HÀŠŠ}Z¦‹¼þò?×ÍÜE7åçòm摐y–á$Š[¾°ÀËH´Ÿ†k¾§'ùÁ‚Oäb{‡ÿ%¾,#€Ö¦ÜÂçmQ‡›±`ú eëbÃÖÀ». Record the mass. We also had to predict the amount of carbon dioxide, water and sodium acetate (NaCH3COO) produced. Put the measured sodium bicarbonate into the crucible. 2) measure out 3mL of sodium bicarbonate with the glass beaker and put that in the crucible, then place the crucible on the clay of triangle. Baking soda is very commonly listed as an ingredient in recipes for baked goods, pancakes and waffles. The other ingredients of the decomposition could be sodium hydroxide, … Chemistry, Period 6, June 12. The decomposition reaction for sodium bicarbonate is given by: The temperature at which decomposition occurs will depend, of course, on the extent of the carbon dioxide and water vapor back pressures. ADI Lab 27 Tiera Nhem. Decomposition of Sodium Bicarbonate See lab report checklist. Production of Sodium Carbonate Lab Decomposition Reactions Introduction As baking soda (sodium bicarbonate) is heated strongly, the following chemical reaction occurs. hai..i have few question regarding this experiment.i have to submit the lab report by monday but till now can get a proper answer to do my discussion part..here is my questions Due to the widespread use of sodium bicarbonate (commonly called baking soda) in many food products, the thermal decomposition reaction has been studied extensively by food chemists. lab experiment on thermal decomposition of sodium bicarbonate? Take out tools (tongs and striker). Purpose: to determine the formula for the product of the thermal decomposition of sodium bicarbonate using masses, mole ratios, and molar masses. Example, thermal decomposition of 1.355 g … PK ! The two steps of the lab are: Decomposition reaction of baking soda (sodium bicarbonate). Among possible reactions, … Make sure that the mass is less than 165 g. 2. law proportions. DO NOT deposit broken glassware in trash, place into broken glassware container located … When it decomposes, carbon dioxide is produced, and this gas produces bubbles in the food that make it "lighter" (less dense). Based on the molecular formula of sodium bicarbonate, three possible reactions (equations 1-3 below) will account for the loss of carbon dioxide gas upon heating. 66 Experiment 13 - Thermal Decomposition of Sodium Bicarbonate NaHCO3 (s) is commonly called sodium bicarbonate. Sodium bicarbonate has a steady rate of decomposition; however, by introducing heat, the energy required to break the bonds is met. 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. Decomposition of Sodium Bicarbonate Investigation. In this lab, you will use stoichiometry to probe the decomposition of sodium bicarbonate. Baking soda and … Stoichiometry Decomposition of sodium bicarbonate Lab - YouTube ڧ~Ӧ - [Content_Types].xml �(� ĕ�n�0E�����1�������e�T�ƞ���m����;IHT�(4�&R͹��g��d�g� Introduction . The effect is caused by the thermal decomposition, which produces carbon dioxide gas to produce a long snake -like ash as a combustion product of the other main component, sucrose. Decomposition of Sodium Bicarbonate Stoichiometry LabObjective:The purpose of this lab is to perform a decomposition reaction and measure the massof the product(s) formed, use stoichiometry to determine which thermal decomposition reactionoccurred during the experiment,and calculate the percent yield and error for your experiment. Based on the Theoretical Yield and the Actual Yield (Table 2), determine which of the three reactions occurred in the decomposition of sodium bicarbonate. Decomposition of Sodium Bicarbonate Background and Purpose: Sodium bicarbonate (sodium hydrogen carbonate) decomposes at around 50 C. One of the products of the decomposition is carbon dioxide, which makes baking soda a popular ingredient in baking. A. Decompose Sodium Bicarbonate, NaHCO 3 (video 1 procedure/skills 1 above) 1. My experimental results tell me the mass of the product to be 1.27 so i produced i small amount less than i should have. The thermal decomposition of sodium bicarbonate, a candidate material for Ilue gas desulfunzation. Sodium bicarbonate is one of the main components of the common "black snake" firework. 2) Weigh out a second 50-60 g sample of sodium bicarbonate by difference. After the thermal decomposition is complete, only sodium carbonate is left as a solid product whereas water and carbon dioxide being gases will escape into the air.
