Sodium Bicarbonate Acetic Acid Equation: Everything You Need To Know

Gallery For > Sodium Bicarbonate And Acetic Acid


Sodium bicarbonate and acetic acid are two common household items that can be found in almost every kitchen. When combined, they create a chemical reaction that produces carbon dioxide gas, water, and sodium acetate. This reaction is commonly used for cleaning, cooking, and even in medical treatments. In this article, we will explore the sodium bicarbonate acetic acid equation and its various applications.

The Chemical Equation

The chemical equation for the reaction between sodium bicarbonate and acetic acid is as follows: NaHCO3 + CH3COOH → CO2 + H2O + CH3COONa This equation can be simplified as: Baking Soda + Vinegar → Carbon Dioxide + Water + Sodium Acetate

How Does It Work?

This reaction is an example of an acid-base reaction, where the acetic acid acts as the acid and the sodium bicarbonate acts as the base. When the two are mixed together, the acetic acid donates a hydrogen ion (H+) to the bicarbonate ion (HCO3-), which creates carbonic acid (H2CO3). The carbonic acid then breaks down into carbon dioxide gas (CO2) and water (H2O). The remaining sodium acetate (CH3COONa) is formed from the sodium ion (Na+) and the acetate ion (CH3COO-).

Applications of the Sodium Bicarbonate Acetic Acid Reaction

This reaction has a variety of applications in daily life. One of the most common uses of this reaction is in cooking. When baking soda is added to vinegar, it creates a carbon dioxide gas that helps baked goods rise. This is why baking soda is often used in recipes for cakes, muffins, and breads. Another use of this reaction is in cleaning. The carbon dioxide produced by the reaction can help to remove stubborn stains and grime from surfaces. For example, mixing baking soda and vinegar can be used to clean ovens, bathroom tiles, and sinks. In addition, this reaction is also used in medical treatments. The carbon dioxide gas produced by the reaction is used in medical procedures such as endoscopy and laparoscopy to inflate the body cavity for better visibility.


The sodium bicarbonate acetic acid equation is a simple but powerful chemical reaction that has a variety of applications in daily life. Whether it’s in cooking, cleaning, or medical treatments, this reaction has proven to be a useful tool for many different purposes. So the next time you reach for baking soda and vinegar, remember the chemical reaction that’s taking place and appreciate its many uses.
