Is Baking Soda Alkaline?

Baking soda is a cooking staple that most people have in their kitchens. But what many don’t know is that baking soda is actually alkaline.

Checkout this video:


Baking soda is a white, powdery substance that is often used as a leavening agent in baking. It is also known as sodium bicarbonate or bicarbonate of soda. Baking soda is alkaline, which means it has a high pH level. When mixed with an acidic substance, it can help neutralize the acid.

What is Baking Soda?

Baking soda is a white crystalline powder (NaHCO3) better known to chemists as sodium bicarbonate, bicarbonate of soda, sodium hydrogen carbonate, or simply baking soda. To an ordinary person like you or me, baking soda is just another one of the many household cleaning products that we use on a daily basis.

But what most people don’t realize is that baking soda is much more than just a simple cleaning product. It has a multitude of uses, both in and out of the home. In fact, you might be surprised to learn that baking soda is actually classified as an alkaline substance.

The confusion surrounding the classification of baking soda arises because it can be used for both acidic and alkaline reactions. When used in conjunction with an acid, such as vinegar, baking soda will act as a neutralizing agent to cancel out the acidic properties of the vinegar. However, when used alone, baking soda will have an alkalizing effect on whatever it comes into contact with.

So, to answer the question – Is baking soda alkaline? The answer is yes… and no. It all depends on how you intend to use it.

The Chemistry of Baking Soda

Baking soda is a chemical compound with the formula NaHCO3. It is a white crystalline solid that is insoluble in water. Baking soda is used as a leavening agent in baking. When it reacts with an acidic ingredient (such as yogurt, lemon juice, or buttermilk), it releases carbon dioxide gas, which causes the batter to rise.

Baking soda is alkaline, with a pH of 8.0. This means that it neutralizes acids. When baking soda comes into contact with an acid, a chemical reaction takes place that produces carbon dioxide gas. This gas makes baked goods light and fluffy.

Baking Soda and Alkalinity

Baking soda is an alkaline compound. When it interacts with an acidic compound, it neutralizes the acids and forms a salt. This reaction is what gives baking soda its leavening properties.

Baking soda is often used as a natural cleaning agent because it is effective at removing dirt, grime, and stains. It is also a gentle abrasive, making it ideal for scrubbing surfaces.

While baking soda is safe to use around the house, it is important to remember that it is a powerful chemical compound. Always use baking soda with care and follow the manufacturer’s instructions.

Baking Soda and pH

Baking soda is a mild alkaline substance. When it is combined with an acidic substance, it can neutralize the acidity and produce a salt. This reaction is the basis for many baking recipes, including cakes and muffins.

The pH of baking soda is 9.0, which means it is slightly alkaline. This makes it a good choice for neutralizing acids like vinegar or lemon juice. It can also be used to control the pH of swimming pools and hot tubs.


We can conclude that baking soda is accessible, cheap, and effective in many situations where an alkaline solution is needed. Though it’s not as powerful as some industrial cleaners, it’s still a useful tool to have around the house.
