Experiment 13 - Thermal Decomposition of Sodium Bicarbonate
66 Experiment 13 - Thermal Decomposition of Sodium Bicarbonate NaHCO3 (s) is commonly called sodium bicarbonate. 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. Among possible reactions, the two following

My evidence shows how the byproducts of the thermal decomposition are most definitely water and carbon dioxide. Since baking soda is sodium bicarbonate, and that when cooking with baking soda it acts like a leavening agent, the gases are acting as byproducts to raise the food, while still leaving the baking soda present even through the chemical reaction process.

Decomposition of Baking Soda Purpose: ... Background: Sodium bicarbonate (baking soda, properly known as sodium hydrogen carbonate) is used in the preparation of many foods. When it decomposes, carbon dioxide is produced, and this gas produces bubbles in the food that make it "lighter" (less dense). For instance, baking soda is often used in baking cakes, in order to make them "rise" as they ...
