Purpose: to determine the formula for the product of the thermal decomposition of sodium bicarbonate using masses, mole ratios, and molar masses. Test your product with red cabbage extract. We also needed to know how to write a balanced chemical equation. The thermal decomposition of sodium bicarbonate, a candidate material for Ilue gas desulfunzation. Based on the Theoretical Yield and the Actual Yield (Table 2), determine which of the three reactions occurred in the decomposition of sodium bicarbonate. Put the measured sodium bicarbonate into the crucible. Record the mass. Your company wants you to determine the correct decomposition reaction that baking soda undergoes. When NaHCO3 is heated above 110 oC (but not heated to "red heat") it has been observed that both H2O (g) and CO2 (g) are evolved by some chemical change, and that after this decomposition is complete, a white solid residue remains. 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. 3-4 hours. The two steps of the lab are: Decomposition reaction of baking soda (sodium bicarbonate). By2³$ŠÅ-êÿ¬HÀŠŠ}Z¦‹¼þò?×ÍÜE7åçòm摐y–á$Š[¾°ÀËH´Ÿ†k¾§'ùÁ‚Oäb{‡ÿ%¾,#€Ö¦ÜÂçmQ‡›±`ú eëbÃÖÀ». Add ≈ 30 g of baking soda (NaHCO 3) to the dish. Turn on the gas for the Bunsen burner and light it using the striker. 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. states that a compound is always made up of the exact same proportion of elements by mass. Materials Baking soda Stirring rod Pipe Stem Triangle Tongs Balance Wire Gauze Bunsen burner set up Crucible Background Due to the widespread use of … states that mass is conserved during a chemical reaction. … òá?²÷%v\cǼZÝò¦Xþûô×¯¾‡Áþëõ«—ÌJÆ"¼?-š™;%ľÿéc=¾Fò•³( Stoichiometry is the study of mass relationships in chemistry. Baking soda is very commonly listed as an ingredient in recipes for baked goods, pancakes and waffles. This will help determine what quantity goes in the mix. Decomposition of Sodium Bicarbonate Investigation. Introduction. Baking soda is commonly used in baking to provide a “rise” to baked goods. Safety for this lab: Wear safety glasses at all times. When it decomposes, carbon dioxide is produced, and this gas produces bubbles in the food that make it "lighter" (less dense). Baking soda is used to prepare cakes in order to ensure that cakes “rise” as they bake. Lab 27. When it is heated above about 80°C it begins to break down, forming sodium carbonate, water and carbon dioxide. Before class starts: Read the lab for the week carefully before you start writing your pre-lab.
