I always like to think that baking soda is my baking soulmate. Whether it’s in a cake, biscuit, cookie, or muffin, no sweet treat is complete without that special something that only baking soda can bring. But what exactly is baking soda, and what is the pH of baking soda?

First of all, let’s define what pH is. pH stands for ‘potential hydrogen’ and it’s a measure of how acidic or alkaline a solution is. A pH of 7 is neutral, while anything below 7 is acidic and anything above 7 is alkaline.

Baking soda or sodium bicarbonate is a naturally occurring mineral crystalline and is considered an alkaline compound. That means its pH should be higher than 7. Most people think that baking soda is a single compound, but it’s actually made up of sodium, hydrogen, and carbonate ions. What this means is that baking soda can help neutralize acids. 

So, what is the pH of baking soda? The pH of baking soda is, on average, 9. This means that baking soda is slightly more alkaline than neutral.

I have to admit, I was surprised at first when I discovered the pH of baking soda. I thought it would have a much higher pH, given that baking soda is known for its ability to neutralize environmental acids. It’s like when I make my delicious chocolate chip cookies. Despite adding all kinds of acidic ingredients like eggs and cocoa powder, baking soda still manages to raise the pH of the batter and neutralize the acid.

This is why baking soda is such a necessary component in almost all baking recipes. Not only does it help to neutralize environmental acids, it also helps give your baking that fluffy and light texture that you so often crave.

Think about that individual crumb of a muffin you had at Aunt Jenny’s last summer and how light it was compared to traditional muffins – that was probably because she was using baking soda in her recipe! Additionally, if you’re curious about the calories in a McDonald’s large fry, I pinned a superb article.

But baking soda isn’t just good for baking – it can be used for medical and even household cleaning purposes. It’s amazing how versatile baking soda truly is. For example, if you have a sore throat, you can mix a teaspoon of baking soda with 8 ounces of water and drink it to help soothe it. You can even use baking soda to wash vegetables or scrub your pots and pans clean!

So, next time you’re inspired by that smell of freshly baked goods, remember you can thank baking soda. With its incredible ability to neutralize environmental acids and give baked goods that light texture, baking soda truly is a miracle ingredient. And don’t forget, the pH of baking soda is, on average, 9.

Understanding pH Of Baking Soda?

First thing’s first: what is pH? Well, pH stands for “potential hydrogen” and is a measure of acidity and alkalinity in liquid solutions. A substance with a pH of 7 is neutral, while anything with a pH lower than 7 is considered acidic and anything with a pH higher than 7 is basic, or alkaline. Carrying that thought, if you’re interested in the amount of calories in birria tacos, I pinned an amazing article lately.

On the pH scale, baking soda has a pH level of around 8.1, making it an alkaline ingredient. This is something that I just recently discovered in my kitchen experiments. After baking a dozen loaves of bread and reading dozens of baking books, I finally had the ah-ha moment – baking soda has a lower pH. 

Understanding the pH of baking soda can help you get the most out of your baking projects. Considering its alkaline nature, it can actually neutralize acids found in ingredients such as buttermilk and sour cream, reducing the acidity of the recipes and giving you the perfect balance.

Before I came across this knowledge, I was never happy with my results – everything was either too soggy or too dry, or not sweet enough, yikes! Keeping that in view, if melting queso fresco is something that grabs your attention, I just pinned a great article. There was always something “off” about my treats and I just thought that my baking skills weren’t up to par, when in reality I didn’t understand the pH of baking soda and its effects on my recipes.

For instance, if you’re baking a cake and use buttermilk or sour cream as one of the ingredients, you can counteract the acidity of those ingredients by adding baking soda. This helps to lighten the cake and makes it more airy, while also making the flavor more mellow. Without the baking soda, the cake would become overly dense and probably taste too acidic.

When baking cookies, the baking soda also plays an important role. It acts like a leavening agent, meaning it helps the cookie dough to rise, making the cookies fluffy and soft. Plus, it can help combat a strong acidic taste and give the cookies the right balance of sweetness and flavor.

Now that you understand the basics of baking soda’s pH, how can you incorporate this knowledge into your recipes? Quite simply, adjusting the pH of baking soda can help you create the perfect flavor balance for your baked goods. Here’s a basic baking soda “pH recipe” that you can follow: 

– Start with 1 Teaspoon of baking soda per 1 Cup of flour

– Taste-test the dough to see if the flavor balance is right

– Add a 1/4 Teaspoon of baking soda for every teaspoon of acidic ingredient

– Taste-test again 

Remember, the pH of your recipe is important and can drastically change the flavor. Too much baking soda can make the food overly alkaline, and too little can leave it overly acidic. Play around with the acidic ingredients in the recipe and adjust the baking soda accordingly.

Following that, does the thought of microwaving Uncle Ben’s rice cross your mind? I just wrote an article about it – so let’s carry on.

Factors affecting the pH of baking soda

As all of you foodies out there know, baking soda is one of the main ingredients for creating tasty baked treats like cakes and cookies. It’s a combination of sodium bicarbonate and a weak mineral acid, so when it’s mixed with liquids it creates bubbles of carbon dioxide. These bubbles help to create a nice rise in baking recipes, and that’s why it’s so important!

But the pH of baking soda matters too. The pH is a measure of how acidic or alkaline a substance is. Baking soda is considered to be a very weak alkaline and has a pH around 9 for the commercial brands you can get in supermarkets. But this can change over time. Here’s how.

The Temperature

The first factor that can affect the pH of baking soda is temperature. Hotter temperatures usually make substances more alkaline, and baking soda is no exception. This is why it’s important to store baking soda at room temperature. If it gets too hot, the pH can end up being too high, and your baking recipes won’t rise properly. I’ve seen this happen first-hand with some of the cookies I’ve made – they didn’t rise as they should have!


Moisture can also have an affect on the pH of baking soda. When baking soda is exposed to air, it tends to absorb moisture from it. This can make it more acidic, and this is why it’s important to store it in an airtight container. I’ve seen the effects of too much moisture on baking soda first-hand too. I made a batch of cupcakes for a birthday one time, and they didn’t rise as much as they should have, probably because the baking soda wasn’t stored properly and had absorbed too much moisture!


Finally, certain chemicals can react with baking soda and change its pH as well. This includes things like chlorine and other cleaning products. I had an experience with this once when I was making a cake for a friend. I put a scoop of baking soda into the mix, only to realize that I’d used some that was stored in a cupboard near the sink and had been exposed to some cleaning products.

The cake didn’t rise properly, and it was only then that I realized it was because the baking soda had been affected by the chemical fumes!

So, there you have it! Those are the three main factors that can affect the pH of baking soda. Keep an eye on these three things and you should be able to use baking soda effectively for all of your baking recipes.
