This isn’t a scientific class. It’s your all-time favorite food blog. Today we discussed what occurs when baking soda and water are combined. Baking soda combines with water to create heat and carbonic acid, which results in the production of carbon dioxide.

Hello there! My name is Shea, and I’m a little obsessed with baking, especially when it comes to the more invasive and tiresome aspects like science. Although I am not the most knowledgeable on baking soda scientific projects, I do know a thing or two about them.

Have you ever wondered what happens when you combine baking soda and water? It may not be as thrilling as combining baking soda with an acid like vinegar, but it is still rather intriguing, and that is what this article is here to tell you today.

Who’s eager to explore the realm of science?

What Happens When You Mix Baking Soda and Water?

When baking soda, also known as sodium bicarbonate (NaHCo3), reacts with water, it produces heat and carbonic acid. This form of heat is classified as exothermic rather than endothermic because:

  • To initiate an endothermic process, heat must be introduced.
  • When there is excess heat, exothermic processes occur.

Since no heat is being supplied to the water, the process is exothermic. The carbonic acid is no longer stable at this stage. Here is where the traditional fizziness comes in. As baking soda combines with water, carbon dioxide is produced, resulting in the famous fizz.

This is the scientific equation: NaHCo3 + H2O = NaOH + H2CO3

Is Baking Soda Added to Water a Chemical or Physical Change?

A prevalent question when investigating what occurs between baking soda and water are whether the interaction is chemical or physical. Baking soda combined with water causes a chemical reaction. This is why.

  • A physical alteration affects just the appearance and not the chemical content.
  • A chemical transformation, on the other hand, changes one material into another (also referred to as a chemical reaction)

It is a chemical change because adding baking soda to water creates a change in the water. Except from the mild and rapid fizziness, the physical makeup of the water remains same. As a result, it is not a physical alteration.

Does Baking Soda Warm Water?

Another often asked issue is if adding baking soda to water raises the temperature. The answer is just marginally. It all stems from an exothermic reaction between baking soda and water.

When baking soda and water combine, an exothermic reaction occurs. Each product’s chemical linkages bind and release energy. This energy subsequently causes the water’s temperature to increase, although insignificantly.

For example, you cannot brew a pot of coffee just by combining baking soda and water. The difference is so little that it is hardly perceptible.


Thus, bakers and scientists, you now know all there is to know about what occurs when baking soda and water are combined. If you’re still not satisfied and want to learn more, read the commonly asked questions below.

What does mixing baking soda with water do?

If you’re wondering what baking soda with water accomplishes when ingested, it’s a terrific treatment for relaxing indigestion, but not on a frequent basis. Every now and again, add a teaspoon of baking soda with a full glass of water to relieve indigestion.

Is mixing water and baking soda a chemical change?

Indeed, combining water with baking soda causes a chemical change since the water’s makeup changes. It does not, however, modify the look of the water, which would result in a physical change.

What are the side effects of baking soda and water?

Although consuming baking soda and water might help relieve indigestion, excessive use can be very hazardous. In the short term, it may increase indigestion, gas, nausea, diarrhea, and stomach discomfort. Hypokalemia, hypochloremia, and hypernatremia may develop over time.

What does baking soda do to your body?

Baking soda (a salt) degrades in the body to generate sodium and bicarbonate, an alkaline solution that neutralizes stomach acid. That is why many people use baking soda and water to relieve dyspepsia.

Final Words

What happens when baking soda and water are combined? A chemical and exothermic reaction occurs, producing carbon dioxide, which causes the water to fizze somewhat. While modest, this shift elevates the temperature of the water.

Why does baking soda not react with water?

Baking soda water does not bubble because it is an alkali, which is the chemical inverse of an acid. When we combine baking powder with water or milk, alkali and acid react to form carbon dioxide bubbles.

What type of reaction is water and baking soda?

Endothermic or exothermic chemical processes exist. Endothermic implies you have to put energy (heat) into the process to make it happen, while exothermic indicates there is energy (heat) left behind. Heat that is left behind will boost the temperature. Since the reaction between baking soda and water is exothermic, the water becomes somewhat warmer.

Is it okay to mix baking soda and water?

It helps to neutralize stomach acids and relieves indigestion in adults. Most health experts swear by combining baking soda with water, which is also an excellent source of heartburn relief when used in moderation.

How much baking soda do I add to water?

Brandon recommends dissolving a teaspoon of baking soda in an eight-ounce glass of water every morning “to assist maintain a good pH balance throughout the digestive system for optimum digestion, minimal acid reflux, and healthy bowel functioning.” …

Is baking soda dissolving in water a chemical change?

Baking soda is easily dissolved in water. When water is evaporated from a baking soda solution, the baking soda remains intact; hence, solubility is a physical attribute. Baking soda decomposes when heated, which is a chemical property.

How do you mix baking soda and water to clean?

Water and Baking Soda

To clean surfaces, mix a paste with 2 parts baking soda and 1 part water and apply immediately or wipe with a cloth.

Does baking soda and water freeze?

Baking soda may be frozen by combining it with water (and food coloring) and freezing it in ice cube trays.

Can baking soda whiten teeth?

Baking soda is an inexpensive and efficient home treatment for tooth whitening. Baking soda is an efficient stain remover and whitening component for dental care, according to research published in The Journal of the American Dental Association.

Is baking soda and water good for upset stomach?

2 teaspoon baking soda in 4 ounces water. Baking soda may alleviate nausea by altering the pH of the stomach juices. Making a nausea-relieving drink is as simple as dissolving 1

Is baking soda good for your skin?

Baking soda has antibacterial and antiseptic effects. When administered topically, it may help decrease the bacteria that causes acne. But, washing your face with baking soda or using it to treat acne is not usually suggested.
