why does baking soda and vinegar explode
One of my favorite experiments as a kid was to create a volcano using baking soda and vinegar. To erupt, the volcano has a bottle with baking soda and red food coloring. When vinegar is poured in, the homemade lava streams out of the volcano on its own! But why do baking soda and vinegar react this way? They react because one is a base while the other is an acid. Acids and bases each have different parts of H2O, or water. Bases contain an OH, or an oxygen and hydrogen atom, which together is known as hydronium. Acids contain the other H, one hydrogen. These really like to join and form water, so they break away from the acid and base to react. In our case, baking soda is sodium bicarbonate (a base) and vinegar is diluted acetic acid. When they react to release the OH and H to become water, they also release carbon dioxide. This makes the reaction bubble and expand, just like when you shake up a can of soda and open it!
Fun fact: You can make invisible ink with equal parts baking soda and water. Hold the paper close to a light bulb (be careful! ) or paint over the paper with grape juice to reveal your message!
How are you when you get home from a day at school? Those are just a few of the adjectives that kids might use to their hunger pains when they through the front door. Instead of starting on, the first stop many kids make is the. If you've ever searched the for food after school, you may have noticed that it also usually contains all sorts of other items that don't make a good. The door full of contains items that are usually only good if they're added to something else. You're also likely to find other items that are used in the cooking process, such as vinegar. You might also find a box of baking soda intended to odors in the.
If you can't find food, you might be to up your own with some of the things you found inside. Before you become a mad scientist in the kitchen, though, you should know that some of those things might not make a tasty treat. Take baking soda and vinegar, for example. Mixing those two ingredients will get you a reaction, but it won't taste good. In the right amounts and containers, the mixture can even be downright! Baking soda and vinegar react chemically because one is a base and the other is an. Baking soda is a basic compound called sodium bicarbonate. Vinegar is a diluted solution that contains acetic. The baking soda and vinegar reaction is actually two separate reactions. The first reaction is the -base reaction. When vinegar and baking soda are first mixed together, hydrogen ions in the vinegar react with the sodium and bicarbonate ions in the baking soda.
The result of this initial reaction is two new chemicals: carbonic and sodium acetate. The second reaction is a decomposition reaction. The carbonic formed as a result of the first reaction immediately begins to decompose into water and carbon dioxide gas. Just like carbon dioxide bubbles in a carbonated drink, the carbon dioxide (that formed as the carbonic decomposed) rises to the top of the mixture. This creates the bubbles and foam you see when you mix baking soda and vinegar. If you mix a large amount of baking soda and vinegar in a small container with a narrow opening, expect an impressive eruption! Many science teachers use this simple chemical reaction to teach students about chemistry. If you've ever made a homemade as a science experiment, then you know firsthand what happens when baking soda and vinegar react!
