Vinegar-baking soda volcano

Do you remember how much fun it was to watch a vinegar baking soda volcano erupt The bubbles of carbon dioxide (CO2) resulted from a decomposition reaction that quickly followed the acid-base reaction between the vinegar (HC2H3O2), an acid, and baking soda (NaHCOs), a base, as shown below. Acid-Base Reaction... 

They ask questions, lots of questions. They love the diversity of science, and they sq)preciate the beauty of science. They may never become professional scientists themselves, but th ll sit at the dining room table someday, laughing and joking with their kids as th help them build vinegar-and-baking-soda volcanoes. 

Did you ever make a day volcano in kindergarten that erupted when filled with vinegar, baking soda, and red food coloring for effect Have you pushed the gas pedal of a car and felt the acceleration as the car moved forward Have you wondered why laxmdry detergents work better than normal soap to clean your clothes Each of these processes involves a chemical reaction—the transformation of one or more substances into different substances. 

You have probably already encountered the reaction of vinegar with baking soda. The carbon dioxide that is produced can be used to simulate a volcano, for example, or to propel a toy car or rocket. 

What can you do with the used baking soda I wouldn t suggest using it in your baking, because heat will liberate the smells. Give it to the kids to build a volcano. Tell them to combine the soda with vinegar and watch it fizz. This may release those bad smells, but you d expect a volcano to be smelly. 

How can I make a volcano from vinegar and baking soda ... 

Remember as a child making that baking soda and vinegar volcano That s chemistry. Do you cook or clean or use fingernail polish remover All of that is chemistry. 1 never had a chemistry set as a child, but 1 always loved science. 

In the classic kindergarten volcano, the baking soda (which is sodium bicarbonate) reacts with acetic acid in the vinegar to form carbon dioxide gas, water, and sodium acetate. The newly formed carbon dioxide bubbles out of the mixture, causing the eruption. Reactions that occur in liquids and form a gas are gas evolution reactions. A similar reaction causes the fizzing of antacids such as Alka-Seltzer . ...
