The reaction between baking soda (sodium bicarbonate) and vinegar (dilute acetic acid) generates carbon dioxide gas, which is used in chemical volcanoes and other projects. Here is a look at the reaction between baking soda and vinegar and the equation for the reaction.

Key Takeaways: Reaction Between Baking Soda and Vinegar

How the Reaction Works

The reaction between baking soda and vinegar actually occurs in two steps, but the overall process can be summarized by the following word equation: baking soda ( sodium bicarbonate) plus vinegar (acetic acid) yields carbon dioxide plus water plus sodium ion plus acetate ion

The chemical equation for the overall reaction is:

with s = solid, l = liquid, g = gas, aq = aqueous or in water solution

Another common way to write this reaction is:

The above reaction, while technically correct, does not account for the dissociation of the sodium acetate in water.

The chemical reaction actually occurs in two steps. First, there is a double displacement reaction in which acetic acid in the vinegar reacts with sodium bicarbonate to form sodium acetate and carbonic acid:

Carbonic acid is unstable and undergoes a decomposition reaction to produce the carbon dioxide gas:

The carbon dioxide escapes the solution as bubbles. The bubbles are heavier than air, so the carbon dioxide collects at the surface of the container or overflows it. In a baking soda volcano, detergent usually is added to collect the gas and form bubbles that flow somewhat like lava down the side of the 'volcano.' A dilute sodium acetate solution remains after the reaction. If the water is boiled off of this solution, a supersaturated solution of sodium acetate forms. This " hot ice" will spontaneously crystallize, releasing heat and forming a solid that resembles water ice.

The carbon dioxide released by the baking soda and vinegar reaction has other uses besides making a chemical volcano. It can be collected and used as a simple chemical fire extinguisher. Because carbon dioxide is heavier than air, it displaces it. This starves a fire of the oxygen needed for combustion.

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 homework, the first stop many kids make is the refrigerator . If you've ever searched the refrigerator for food after school, you may have noticed that it also usually contains all sorts of other items that don't make a good after-school snack.

The door full of condiments 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 refrigerator .

If you can't find food, you might be to up your own concoction 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 volcano as a science experiment, then you know firsthand what happens when baking soda and vinegar react!
