Why Does Vinegar And Baking Soda React | 4 Easy Steps

Understanding the Reaction Between Vinegar and Baking Soda

Vinegar and baking soda have been used in countless science experiments and household cleaning tasks. This simple combination causes an exciting reaction that leaves many curious about the science behind it. Let’s delve deep into the chemistry of this classic acid-base reaction.

Step 1: Introduction to Acids and Bases

  • Acids are substances that can donate a proton (H+) to another substance.
  • Bases, on the other hand, can accept a proton. Vinegar, primarily composed of acetic acid, and baking soda (sodium bicarbonate) represent this acid-base duo.

Step 2: What Happens at the Molecular Level?

When vinegar and baking soda mix:

  1. Acetic acid in the vinegar reacts with sodium bicarbonate.
  2. This reaction produces carbonic acid, which quickly decomposes.
  3. The decomposition leads to the release of carbon dioxide gas (the bubbles you see) and water.

Step 3: Why the Reaction is Important Beyond the fun visual display, this reaction has practical applications:

  1. In cooking, as a leavening agent making baked goods rise.
  2. In cleaning, where the effervescence helps in breaking down stains.
  3. As a basic scientific demonstration for children and adults alike.

Step 4: Variables that Affect the Reaction Temperature play a role

A colder environment might slow down the reaction, making the release of carbon dioxide gas less vigorous. On the contrary, a warmer environment could speed it up.

Answers To Questions:

What happens when vinegar reacts with baking soda?

When vinegar (an acid) reacts with baking soda (a base), it produces carbon dioxide gas, water, and sodium acetate. The fizzing and bubbling you observe is the carbon dioxide gas being released.

Why does vinegar and baking soda react for kids?

For kids: Imagine vinegar and baking soda as two people who really want to dance. When they meet, they start dancing and create bubbles in the process. This “dance” is a special kind of reaction where vinegar, which is sour like lemon juice, and baking soda, which is a bit like powder in a cake, come together to make bubbles!

Why does baking soda and vinegar react cold?

The reaction between baking soda and vinegar can feel cold because the reaction is endothermic. This means it absorbs heat from the surroundings. So, when the two ingredients mix, they take in a bit of warmth from around them, making the mixture feel cooler.


The reaction between vinegar and baking soda has intrigued many over the years, from curious children to adults. It’s not just about the visible effervescence, but the underlying science of acid-base reactions. This experiment offers a fantastic gateway to understanding basic chemistry concepts while also serving practical purposes in daily life. Whether it’s for cleaning, cooking, or pure educational fun, the combination of vinegar and baking soda continues to amaze and educate.

What Happens When You Mix Baking Soda And Vinegar

Baking soda (scientifically known as sodium bicarbonate) and vinegar (which contains acetic acid) represent a classic acid-base combination. When these two compounds come into contact, an effervescent reaction occurs, but what’s really happening beneath those bubbles?

Step 1: Understanding the Basics

The Players:

  1. Baking Soda (Sodium Bicarbonate): A basic compound found in many households. It’s often used for baking, cleaning, and deodorizing.
  2. Vinegar: A weak acid, usually made by fermenting ethanol with acetic acid bacteria. It has culinary and cleaning applications.

The Reaction:

CH3COOH(aq)+NaHCO3(s)→CH3COONa(aq)+H2O(l)+CO2(g) Acetic Acid + Sodium Bicarbonate → Sodium Acetate + Water + Carbon Dioxide

Step 2: Setting Up Your Experiment


  • Baking soda
  • Vinegar (white or apple cider vinegar work best for a clear observation)
  • A measuring spoon
  • A clear glass or bowl


  1. Measure a spoonful of baking soda and add it to the clear glass or bowl.
  2. Slowly pour vinegar into the bowl with the baking soda.

Step 3: Observing the Reaction

As you pour the vinegar, you’ll notice an immediate bubbling and fizzing. This is the carbon dioxide gas being released. The reaction is both swift and evident.

Step 4: Delving Deeper

As per the chemical equation mentioned earlier, the acid (vinegar) and the base (baking soda) combine to produce salt (sodium acetate), water, and carbon dioxide gas. The effervescence you observe is a result of this carbon dioxide escaping the solution.

Step 5: Practical Applications

  1. Cleaning: The effervescent action can help dislodge grime and dirt, making it an effective cleaner for certain surfaces and drains.
  2. Baking: The carbon dioxide produced can act as a leavening agent, causing dough to rise.
  3. Education: It’s a simple and effective way to introduce children to basic chemistry concepts.

Step 6: Factors Influencing the Reaction

Temperature: The reaction might be more vigorous in warmer conditions. Conversely, colder environments might slow down the reaction.

Concentration: Using concentrated vinegar (more acetic acid content) can result in a more pronounced reaction.

Step 7: Safety Precautions

While the reaction is generally safe, it’s essential to:

  • Avoid direct ingestion of the mixture.
  • Ensure the experiment is performed in a well-ventilated area to avoid inhaling excessive carbon dioxide.
