Mixing lemon juice with baking soda is more than just a fun science experiment. This simple combination of two everyday ingredients leads to a fascinating chemical reaction, which has applications in health, cleaning, skincare, and even the kitchen. The fizzing and bubbling result from the reaction between the citric acid in lemon juice and the sodium bicarbonate in baking soda. But beyond the reaction itself, there’s so much more to discover about how this combination can be used in daily life.
In this article, we’ll explore the science behind the reaction, the health benefits and risks of using lemon juice and baking soda, practical applications, and answer some common questions about this powerful duo.
Understanding the Chemical Reaction Between Lemon Juice and Baking Soda
When you mix lemon juice with baking soda, you witness a classic acid-base reaction. Here’s what happens:
- Lemon juice contains citric acid, which gives it a low pH and makes it an acidic substance.
- Baking soda is a base, known scientifically as sodium bicarbonate.
- When an acid (citric acid) reacts with a base (sodium bicarbonate), they neutralize each other. This reaction releases carbon dioxide (CO2) gas, which is what creates the bubbles and fizz.
The neutralization reaction also produces water and sodium citrate, a type of salt. This fizzing effect is similar to what happens when you mix vinegar with baking soda, another popular experiment.
Chemically, the reaction looks like this: Citric acid+Sodium bicarbonate→Carbon dioxide (CO2)+Water (H2O)+Sodium citrate\text{Citric acid} + \text{Sodium bicarbonate} \rightarrow \text{Carbon dioxide (CO2)} + \text{Water (H2O)} + \text{Sodium citrate}Citric acid+Sodium bicarbonate→Carbon dioxide (CO2)+Water (H2O)+Sodium citrate
The bubbling reaction is visually exciting and demonstrates the interaction between an acid and a base. You can experience a similar reaction in cooking when you use ingredients like baking soda and lemon juice in cakes or pastries.

The Health Benefits of Lemon Juice and Baking Soda
Beyond its scientific curiosity, the mixture of lemon juice and baking soda has been touted for its potential health benefits. Let’s break down some of the most commonly discussed benefits and whether they hold up.
1. Detox and Alkalizing Properties
One of the most popular claims about the mixture of lemon juice and baking soda is its ability to detoxify the body and balance pH levels. Proponents of this mixture suggest that while lemon juice is acidic, once it’s metabolized, it has an alkalizing effect on the body. This is thought to help reduce overall acidity in the blood and tissues, promoting better health.
However, the science behind these claims is mixed. The body regulates its pH levels very tightly, and diet plays a minor role in altering the body’s internal pH. While this mixture may have short-term effects on digestion, it’s unlikely to significantly change your body’s pH levels. That said, drinking a small amount of the mixture in water can still help neutralize acid in the stomach, offering relief for those with occasional heartburn or indigestion.
2. Aiding Digestion and Reducing Bloating
Another widely mentioned benefit is the mixture’s ability to aid digestion. When you drink lemon juice and baking soda mixed in water, the sodium bicarbonate can act as an antacid, neutralizing stomach acid. This can provide relief from bloating, indigestion, and acid reflux.
However, while it may offer short-term relief, overconsumption of the mixture can cause digestive issues. Drinking large amounts regularly can disrupt the body’s natural acid production, potentially leading to more long-term digestive problems. Moderation is key.
3. Skin Exfoliation and Brightening
The combination of lemon juice and baking soda is often used in skincare as a natural exfoliant. The abrasiveness of baking soda helps remove dead skin cells, while the acidity of lemon juice can lighten dark spots and brighten the complexion.
Here’s how you can make a DIY exfoliant:
- Mix one teaspoon of baking soda with one teaspoon of lemon juice.
- Gently massage the mixture onto your skin in circular motions for about a minute.
- Rinse with warm water and apply moisturizer.
However, be cautious when using this mixture on your face. The acidity of lemon juice can irritate sensitive skin, and overuse may cause dryness or even burns. Always perform a patch test on a small area of skin before applying it to your face.
4. Teeth Whitening
Some people use a combination of lemon juice and baking soda as a natural teeth whitener. The abrasiveness of baking soda helps scrub away surface stains, while the acidity of lemon juice can enhance the whitening effect.
While this method may show short-term results, it’s important to use it sparingly. The acidity of lemon juice can weaken enamel over time, making your teeth more sensitive and prone to decay. A safer alternative for long-term teeth whitening is using baking soda alone or opting for commercial whitening products designed for daily use.
