Does Baking Soda Absorb Moisture? (All You Need to Know)

Baking soda or sodium bicarbonate is a crystal salt that has numerous applications. The chemical formula of baking soda is NaHCO3which contains sodium (Na+) cation and bicarbonate(HCO3) anion. Baking soda generally remains in white solid powder form.

There is a major curiosity regarding whether or not baking soda absorbs moisture. This article will provide an in-depth answer and offer you deep insights into the moisture absorption property of baking soda.

Does baking soda absorb moisture?

Baking soda naturally absorbs moisture from its surroundings. Baking soda will absorb moisture from moist air and make the air dry and less humid. For this reason, it can be used as a dehumidifier. Baking soda absorbs water and solidifies after soaking up moisture from the environment.

Baking soda naturally absorbs moisture content from its surroundings. Baking soda is a power like crystalline salt element. Salts tend to dissolve in water solution and form ions. Much like any other salt, baking soda also gives a similar reaction in the presence of water.

Baking soda is a hygroscopic material, and the nature of the hygroscopic elements is, they easily tend to absorb moisture from their surroundings. That’s why Baking soda easily absorbs excess air moisture and makes the air dry.

One application of baking soda is to soak up the humid air from the environment and produce dry and less humid air around a restricted small area.

Baking soda is used to soak up moisture molecules from various types of products. Some are listed here:

In carpet:

Baking soda powder is applied over the damp carpet. A sufficient amount of baking soda is used to soak up all the excess air from the carpet. Baking soda powder is placed on the carpet for several hours to absorb the moisture.

From the air:

Baking soda naturally absorb moisture from the air. Baking soda powder will take several hours up to days to soak up all the moisture from humid air. The powder gradually hardens due to the air moisture.

In-car:

Baking soda is a great dehumidifier, and it can be used to absorb the moisture inside the car. Putting one or two canisters of baking soda powder inside the car will be enough to soak up all the moisture.

From mattress:

Mattress is especially prone to water absorption. Putting one or two canisters of baking soda over the mattress will be enough to absorb all the watery content from the mattress.

From wood:

Moisture gets easily trapped inside the wood. Moisture is the primary cause of wood rot. Baking soda will naturally soak up all the water moisture from the wood.

In the closet:

Baking soda powder is applied to dry and humidify the air inside the closet. Putting one or two packets of baking soda powder will be enough to do the job.

In shoes:

Baking soda is an excellent dehumidifier, and placing a few sprinklings of powder into the shoes will absorb all the moisture.

In the fridge:

Moisture is usually trapped inside the fridge. High moisture content might be damaging for the products. Putting some baking soda into the fridge will effectively remove moisture.

From fabric:

Little sprinklings of baking soda will erase moisture from clothes and fabrics.

Why does baking soda absorb moisture?

Baking soda is a hygroscopic material that means it absorbs water moisture from the surroundings. Baking soda is a salt crystal. It contains sodium ions and bicarbonate ions. Baking soda absorbs moisture because –

Salts are water-soluble:

Salts are naturally dissolved in water, and they tend to attract water molecules. Salt can be dissolved in water because they form ions when mixed in water.

Chemical and structural composition of baking soda:

The chemical composition and structure of baking soda contribute to its water solubility. And that’s why baking soda can absorb moisture.

Molecular property of baking soda:

Baking soda easily attracts water from its surroundings. And like any other salts, the molecules in the baking soda show similar properties such as water solubility and moisture absorption.

Ability to form ions:

Salts form ions when in contact with water. Baking soda is a salt crystal and exhibits properties similar to any other salt molecule. Baking soda breaks into sodium (Na+) cation and bicarbonate (HCO3) anion when dissolved in water. 

For this reason, baking soda absorbs moisture from its surroundings.

How long does it take for baking soda to absorb moisture?

It takes from one to two hours to 24 hours for baking soda to absorb moisture from the air. To absorb moisture from a smaller area, a few sprinkles of baking soda is enough. After the sprinkling of baking soda power, it is best to leave it there for 1 day.

But to clear the moisture from the air inside a restricted area, one to three canisters of baking soda powder are required. Baking soda will harden by soaking up damp air. That’s why it is better to replace the canisters after a while.

Baking soda will soak up moisture from straight surfaces such as drawers, floors, tables, selves within a few hours. You have to sprinkle the baking soda on the surface and rest it there for a while.

Applying baking soda on steep surfaces is somewhat difficult as you will need to secure the baking soda over the vertical surfaces. In that case, you would prepare a mixture of soda and water paste. You have to ensure that the paste must stick to the steep surface.

How to use baking soda to absorb moisture?

Baking soda absorbs moisture from the air. Moisture easily damages houses and household products. Using baking soda can be a feasible option to remove moisture from houses and household products.

It is cost-effective to dehumidify houses, mattresses, cars, carpets, closets, woods, fabrics, etc. You have to apply baking soda correctly to absorb moisture.

Step by step procedures of using baking soda in order to absorb moisture are mentioned hereafter –

  • Pour a chunk of baking soda into a bowl.
  • Cover the opening of the bowl using a thin cloth.
  • Put the baking soda in various places of the house to dehumidify your home.
  • you want to dehumidify the clothes, food items, and little products, sprinkle the baking soda over them. It will take away moisture from all items.

Can baking soda be used as a dehumidifier?

Baking soda has versatile applications. Among them, baking soda can be used as a dehumidifier. Baking soda is a hygroscopic salt element that naturally soaks up water from the air.

Baking soda powder will absorb all the water from its surroundings. Baking soda powder is placed near a product, and it keeps the product free from moisture. Baking soda readily dissolves in water and forms ions in the presence of water molecules.

Besides, using baking soda as a dehumidifier is cost-effective. There are other expensive dehumidifiers available in the market compared to the low-cost baking soda. Baking soda provides equal or better moisture absorption in comparison with the other dehumidifiers.

Thereby, the reasonable way is to use baking soda to dehumidify places and products.

What naturally absorbs moisture?

Hygroscopic materials are renowned for their moisture absorption property. All the hygroscopic elements naturally absorb water from the air. Those elements easily form hydrogen bonds with the water molecule.

Baking soda, rock salts naturally dehumidify the air. Their ability to easily soak up moisture from the air makes them natural dehumidifiers. Moreover, pathogens can’t easily grow in a dry area.

Rock salts absorb moisture from the air and store the watery molecules inside them. All types of salts, including sodium chloride, calcium chloride, absorb moisture from the air.

Other hygroscopic elements such as honey, glycerin, ethanol, methanol, sodium hydroxide, etc., naturally attract water from the surroundings. Those elements naturally attract and store water through the absorption method.

Does baking soda attract water?

Baking soda is a hygroscopic material and attracts water. Baking soda also shows water solubility when dissolved in the water solution. It is composed of salt crystals that attract water from the surrounding air.

Baking soda attracts water because the molecules in baking soda chemically react with the water molecules. And predominantly, baking soda is a hydrophilic element that shows water solubility.

When in contact with the air, the salt molecules participate in a chemical reaction with water. The reaction eventually leads to salt’s cation and anion formation. In such a way, baking soda directly attracts water.

Baking soda is used to dehumidify a house, room, carpets, mattresses, cars, etc. Water absorption from air leads to hardening and cake formation of salt. Baking soda not only absorbs moisture from the air but also stores the water into the molecules.

Final Thoughts

Baking soda absorbs moisture from the surrounding air. Baking soda shows water solubility and naturally attracts water. For this reason, baking soda is used to dehumidify houses and products. The natural moisture absorption capacity of baking soda makes it an ideal dehumidifier.
