![]() ![]() Add the mass of the empty plate to the mass of the baking soda to calculate their combined weight.Then zero the scale again and add 15 grams of baking soda with a spoon.Preheat your kitchen oven to 200 degrees F (about 93 degrees C).Digital scale (preferably with 0.1-gram increments).You can actually measure this loss-get some baking soda, and find out how in this activity! Both carbon dioxide and water are gaseous at the warm temperature, which means that they will disappear into the surrounding air. ![]() Only sodium carbonate will remain as a solid product. The produced carbon dioxide gas makes baked goods rise! The higher the temperature of the sodium bicarbonate, the faster it will decompose. ![]() You use this reaction every time you cook and bake. At temperatures above 176 degrees Fahrenheit (80 degrees Celsius), sodium bicarbonate starts to break down into three compounds, forming sodium carbonate (Na 2CO 3), water (H 2O) and carbon dioxide (CO 2). The dark glass reduces the amount of light that reaches the chemical or medicine and therefore prevents light-induced decomposition of the chemical.īaking soda, or sodium bicarbonate (NaHCO 3), is a chemical that can undergo a decomposition reaction when heated. Oftentimes, you do not want a chemical to decompose, because its chemical nature will change. When chemicals are exposed to enough energy, which can be in the form of heat, radiation, electricity or light, they will decompose, however.ĭecomposition reactions are the reason why some chemicals or prescription medicines are stored in dark glass bottles. You have to put in a lot of energy to break their chemical bonds. Most chemical compounds are pretty stable and do not decompose spontaneously. When a chemical substance decomposes it breaks down to form two or more separate compounds. Another reaction type is the decomposition reaction, which is the opposite of a synthesis reaction. One of them is called a decomposition reaction, which makes baking soda lose weight! Want to find out how it works?Ĭhemicals can undergo many different reactions, such as synthesis reactions that create new substances, or combustion reactions, in which a substance usually reacts with oxygen and generates energy in the form of heat. There are many more chemical reactions, however, that you can explore with the help of baking soda. You have probably heard about and maybe even used the baking soda–vinegar reaction to make homemade volcanoes erupt, shoot bottle rockets up in the air or to detect acids and bases. Baking soda is not only great for cooking, but it is also a useful chemical for science projects. ![]()
