What is the pH of baking soda?

In this brief article, we will provide you with the answer to the question: “What is the pH of baking soda?”, discuss what pH is and the applications of baking soda.

What is the pH of baking soda?

Baking soda (sodium bicarbonate, often known as NaHCO3), is a salt made up of bicarbonate ions and sodium ions. It can be found as crystals, although it is more commonly found as a fine powder with good solubility. When it comes into contact with water, it produces a somewhat basic solution with a pH of about 8.6.

Sodium bicarbonate is a fantastic assist in cleaning settings and textiles, in addition to its pharmacological and culinary applications. The product offers anti-stain, anti-mold, and anti-odor properties.

What does pH mean?

pH is an abbreviation for “Hydrogenenic Potential,” a logarithmic scale that evaluates the acidity, neutrality, or alkalinity of a solution.

The pH of any material fluctuates depending on its temperature and content (concentration of acids, metals, salts, etc.).

The scale ranges from 0 to 14, with 7 being the neutral value. The highest acidity is represented by the value 0 (zero), whereas the maximum alkalinity is represented by the value 14. In some compounds, values less than zero or more than 14 can be validated.

What are the applications of baking soda?

Stabilizer for bleach water

For sanitizing, baking soda can be added to bleach water as a stabilizer. A dose of 0.8 – 1.0 percent is recommended.

It improves cleaning

When added to laundry detergents, it improves detergency, bleaching, and alkalizing power. A dose of 0.5 – 0.8 percent is recommended.

In the textile industry, baking soda can be used as pH control, printing absorption agent, and fabric bleaching agent.

Pool treatment

For pool treatment, it increases overall alkalinity, which maintains pH stability, hence preventing corrosion and providing crystal clear water.

The purpose of baking soda is to keep the pH of the pool water stable. The pH stabilization would avoid abrupt fluctuations in the pH of the water produced by pollutants such as acid rain and water supply from artesian wells or mines, among other things.

Sodium carbonate and sodium bicarbonate are chemically distinct compounds with similar functionalities. Sodium bicarbonate is widely used in the swimming pool industry.


For example, it can aid in the fermentation of dough while cooking by releasing carbon dioxide. 


It has a mild abrasive and whitening effect, which makes it useful in the industrial composition of toothpaste. 


The powdered baking soda absorbs scents from the surroundings. As a result, it is a good idea to keep it in a tiny cup inside the refrigerator or on the shoe rack.

It is an excellent powder deodorant in personal hygiene. It has the ability to neutralize acidity and unpleasant smells induced by perspiration. 

Water and bicarbonate solutions’ gentle basic composition makes them effective not just for combating acidic foul smells, but also for molds and fungus that thrive in acidic environments. 

Baking soda powder has the potential to change the pH of the surface it is applied to. It improves the action of detergents and may be used to clean bottles, plates, and rusted objects.

Baking soda combinations

Baking soda and vinegar should not be mixed since one cancels out the other. If you wish to make cleaning solutions for spraying, you must first mix baking soda or vinegar with water. 

However, start by sprinkling the bicarbonate over a tiny surface. The addition of a few drops of vinegar induces a chemical reaction that may be used to remove dirt stains and soften encrustations.

The same mixture may be used to clean and unblock home discharges one after the other. Alternating the use of vinegar and baking soda to surfaces can also aid in the removal of odors. Specifically, those found in the urine of dogs and cats, which can be acidic or alkaline.

Citric acid or lemon juice can be used instead of vinegar.

The body produces NaHCO3, which is a powerful buffering ingredient. When combined with any acid, it emits carbon dioxide and water. Its most well-known application is as a stomach antacid. It is capable of neutralizing excess acid from gastric juice.
