A Very Common STEM Reaction

Baking Soda mixed with Vinegar. Two household products that have been entertaining kids around the world for decades due to their reaction with one another. When teaching science and STEM, the balloon being blown up by this reaction is probably one of the first demonstrations kids will try.

But what is actually going on behind the scenes that causes this visually pleasing reaction?

Why Do Vinegar & Baking Soda React? (1)

Reaction Explained Simply

The reaction is known as an 'Acid-Base' reaction.

Baking soda is a base, and vinegar is an acid. Vinegar isn't just an acid, it is an acid in water, which is important.

The water in the vinegar acts as a host where the base and acid react. During the reaction, when the baking soda is mixed with the vinegar, the baking soda (Base) takes a proton from the vinegar (Acid). The reaction causes the baking soda to transform into water and carbon dioxide. The carbon dioxide is a gas which is released during the reaction, which gives it the bubbling effect, and it expands which will blow up balloons as you have probably seen in some experiments and demonstrations.

Vinegar + Baking Soda Video

Here is a great video demonstrating the reaction of vinegar and baking soda. It explains what has happened simply, and also demonstrates how the reaction can blow up a balloon.


The Reaction Explained in Complex Form

For the full and detailed explanation of what actually takes place when you mix vinegar and baking soda, we researched from professional scientists.

The best answer we could find was here: UCSB ScienceLine

Baking soda is sodium bicarbonate: each molecule of baking soda contains a sodium atom, a hydrogen atom, an oxygen atom, and a carbon dioxide molecule.

Vinegar contains acetic acid, each molecule of which contains a hydrogen atom, and an acetate ion.

When combined, the hydrogen atom in the acetic acid meets up with the hydrogen and oxygen atoms in the baking soda to form a molecule of water, while the acetate ion grabs onto the sodium atom and forms a salt, sodium acetate. The carbon dioxide molecule, free of its other chemical bonds, can now escape and bubbles forth as a gas.

KARLmy brain is not brainingReplyUser CommentThank you :3Replyjosie galvthis is very helpfullReplyChloeI am a school student doing a progect in this topic and this really helped me with writing my research paper.ReplybossthanksReplyperpetua peiris from sri lanka this demonstration helped me a lot in my school projectReplyHenry DavisIt's safe to say ingesting the two would have deadly consequences? Just looking for more ways to detox the human body...Reply

griffin

agreed

YindoWoooooooow!ReplyBVery interesting i am actually doing this experiment for schoolReplysageI was researching why this expirement always ends the way it dose for a school project and now I know why! thank you so much for making this so easy and fun!ReplyObaniThis is very nice I like how they explained everything.ReplyMaddieThank you so much for this explanation. I was searching everywhere to get a description of the molecules for my science class and this said it perfectly. I could easily understand it yet it still was scientific and informative. Thank you so much for creating this and know you made my life a whole lot easier.ReplyMandyThank you so much for the vid!ReplyMandyThis is great thank you!ReplyPaul StevensonI've heard this before, and what I do not understand is why people believe when these ingredients are mixed that they create a cleaning solution. It appears to me, if mixed together and the outcome is water, then you are simply cleaning with water. ??????ReplyUser CommentThis was extremely helpful! Thank you!ReplyMadelinethanks! i have to write an explanation text on an experiment about this for school and this was really helpful to gather information!Reply

jv

thanks alot this helped me alot

NovaThanks for the video! I am trying to do a experiment for school and I think this video helped me! Well..kinda at least!ReplyUser CommentThank you for this video! Our experiment would be to see what happens if we heat it up.ReplyUser CommentAll of these scientific names and chemicals are giving me a headache! LOLReply

Why Do Vinegar & Baking Soda React? (2024)

FAQs

Why Do Vinegar & Baking Soda React? ›

Baking soda and vinegar react chemically because one is a base and the other is an acid. Baking soda is a basic compound called sodium bicarbonate. Vinegar is a diluted solution that contains acetic acid. The baking soda and vinegar reaction is actually two separate reactions.

How does baking soda react with vinegar? ›

The mixture quickly foams up with carbon dioxide gas. If enough vinegar is used, all of the baking soda can be made to react and disappear into the vinegar solution. The reaction is: Sodium bicarbonate and acetic acid reacts to carbon dioxide, water and sodium acetate.

Why does baking soda and vinegar do that? ›

Mixing vinegar and baking soda causes an immediate chemical reaction. This reaction forms water, sodium acetate (a salt) and carbon dioxide – the fizzy part. The amount of carbon dioxide gas that is produced from baking soda is remarkable – one tablespoon (around 18 grams) can release over five litres of gas!

When vinegar and baking soda react together? ›

When vinegar reacts with baking soda, it creates carbon dioxide bubbles, which act as leavening agents. So as the batter bakes, these tiny bubbles expand, causing the cake to rise and giving it that light, airy texture we all love.

Why do baking soda and vinegar cancel each other out? ›

Bases and acids naturally react with one another, and baking soda and white vinegar are no exception. In this interaction, the white vinegar “donates” a proton to the soda. A chemical reaction ensues (this is the fizzing you see when you mix the two substances). This reaction is called neutralisation.

Is it okay to mix vinegar and baking soda? ›

Combining these two common household substances can produce incredible results in the kitchen, but it's important to not combine them in equal amounts because you need to keep the mixture in either the acidic or basic side of the neutral value.

Is vinegar and baking soda safe for drains? ›

Yes, baking soda and vinegar can be safely used to unclog drains. Both ingredients are natural, non-toxic substances that do not harm the environment or the pipes. Furthermore, this combination is a safer alternative to chemical drain cleaners, which can cause damage to pipes and harm aquatic life.

Can you put vinegar and baking soda in your bath water? ›

Apple Cider Vinegar and Baking Soda Bath

By using these two ingredients together, you can maximize the effect of your bath. To make a soothing bath, mix ½ cup of baking soda and ½ a cup of ACV powder. Follow the same directions as for the elementary baking soda bath.

Can I add baking soda and vinegar to my laundry? ›

With baking soda: Vinegar and baking soda neutralize each other, so you won't get the benefits of either if you run them simultaneously. You can, however, add baking soda to your laundry in the wash cycle and white vinegar to the rinse cycle—just don't add them anywhere together.

Can you mix vinegar and baking soda to clean mold? ›

The important thing is to mix the baking soda and vinegar in a 2:1 ratio (that is, twice as much baking soda as vinegar). This method eventually involves vigorous scrubbing with a gritty paste, which may damage softer materials like wallboard or finished wood.

Can you reverse baking soda and vinegar? ›

When you mix substances together, they may change to form a new substance. Sometimes the change is reversible, while at other times it is irreversible. For example, when vinegar is mixed with baking soda, the two fizz and a new substance is formed. This change is irreversible.

Do baking soda and vinegar make hydrogen? ›

Vinegar is made up of hydrogen, carbon, and oxygen atoms. When you mix baking soda and vinegar together, two hydrogen atoms move from the vinegar to the baking soda to create a salt called sodium acetate. The remaining atoms create a new acid—but it breaks down quickly into water and carbon dioxide gas.

Why does vinegar and baking soda inflate a balloon? ›

creating a chemical reaction and blowing up their balloon. SCIENCE: When baking soda and vinegar are mixed together, it creates a gas called carbon dioxide. The gas begins to expand in the bottle and starts to inflate the balloon. The more gas that is created, the larger the balloon will inflate.

What gas does mixing vinegar and baking soda make? ›

When you combine the solid (baking soda) and the liquid (vinegar), the chemical reaction creates a gas called carbon dioxide. Carbon dioxide is invisible, except as the bubbles of gas you may have noticed when the vinegar and baking soda mixture began to fizz. This gas is what made the balloon inflate.

Can you mix vinegar and baking soda to clean fruit? ›

Use either apple cider vinegar or white vinegar to clean your fruits or veggies; both are effective at getting rid of bacteria. Then, pour 1 cup of vinegar (237 ml) into the bowl for every 2 cups (473 ml) of cool water inside. Add 1 teaspoon (6 g) of baking soda for every 2 cups (473 ml) of water.
