Sodium Sulphate Anhydrous Vital Minerals

The Basics of Anhydrous Sodium Sulfate

Anhydrous sodium sulfate, also known as Glauber’s salt, is a chemical compound commonly used as a drying agent. It has a molecular formula of Na2SO4 and is an odorless, white crystalline solid. When exposed to air, it can absorb moisture and become hydrated, which can reduce its effectiveness as a drying agent. This is why it is often used in combination with other drying agents, such as silica gel or calcium chloride.

Why Use Anhydrous Sodium Sulfate?

Anhydrous sodium sulfate is a popular drying agent because it is affordable, readily available, and effective at removing water from a wide range of substances. It is commonly used in the production of pharmaceuticals, food products, and industrial chemicals. It is also used in the laboratory to dry solvents and other organic compounds.

The Benefits of Using Anhydrous Sodium Sulfate

One of the main benefits of using anhydrous sodium sulfate is its ability to remove water quickly and efficiently. It is also non-toxic, non-flammable, and non-reactive with most substances, making it a safe and versatile drying agent. Additionally, it is easy to obtain and store, making it a cost-effective choice for many applications.

Dry Over Anhydrous Sodium Sulfate: How It Works

When using anhydrous sodium sulfate as a drying agent, the substance to be dried is typically placed in a container with the drying agent. The container is then sealed and left undisturbed for a period of time, allowing the anhydrous sodium sulfate to absorb the moisture from the substance. Once the desired level of dryness is achieved, the substance can be removed from the container.

Tips for Using Anhydrous Sodium Sulfate

When using anhydrous sodium sulfate as a drying agent, it is important to keep a few tips in mind. First, make sure to use the appropriate amount of drying agent for the substance being dried. Too little drying agent can result in incomplete drying, while too much drying agent can lead to over-drying and potential damage to the substance. Additionally, it is important to use a container that is air-tight to ensure that the drying agent remains effective.


In conclusion, anhydrous sodium sulfate is a popular and effective drying agent that is used in a variety of industries and applications. Whether you are producing pharmaceuticals, drying organic compounds in the laboratory, or simply trying to remove moisture from a product, anhydrous sodium sulfate is a reliable and cost-effective choice. By following the proper procedures and tips for using this drying agent, you can ensure that your products are properly dried and ready for use.
