What is Sodium Hydroxide?

Sodium hydroxide (NaOH) also known as caustic soda is a caustic hydroxide used in industry (mainly as a base, in the manufacture of paper, fabrics and detergents. In addition, it is used in the oil industry in the preparation of water-based drilling muds At the domestic level, its utilities are recognized for unclogging kitchen and bathroom drains, making homemade soap, etc. In the food industry, it is used as an additive in the preparation of various baked goods.

At room temperature, sodium hydroxide is an odorless white crystalline solid that absorbs moisture from the air (hygroscopic). It is a manufactured substance. When dissolved in water or neutralized with an acid, it releases a large amount of heat which may be sufficient to ignite combustible materials. Sodium hydroxide is very corrosive. It is generally used in solid form or as a 50% solution.

Sodium hydroxide is a highly corrosive base that breaks down proteins at normal room temperature and can cause severe chemical burns. It is very soluble in water and readily absorbs moisture and carbon dioxide from the air.

As one of the simpler hydroxides, sodium hydroxide is often used in combination with neutral water and hydrochloric acid to demonstrate the pH scale to chemistry students.

Sodium hydroxide is used in many industries: in pulp and paper manufacturing, textiles, drinking water, soaps and detergents, and as a drain cleaner.

What is Sodium Hydroxide used for?

Sodium hydroxide is used to make soap, crayons, paper, paint, and petroleum products.

Therefore, always wear safety goggles. You also want to prevent chemicals from ending up on your skin, which is why it is important to always use good gloves or disposable gloves.

Respiratory protection is necessary for volatile substances, vaporous liquids and solids that dust. There are many different types of filters, so you should always refer to the MSDS to find out which filter you need. Many filters also specify which substances they are for.

In some cases it may be necessary to protect the whole body, in which case a plastic overall is needed, you can find it here.

When working with flammable and oxidizing substances, it is important to always have fire extinguishers and absorbents at hand. It is also useful to be able to clean up spills of aggressive chemicals immediately with absorbents and to dispose of them in accordance with international and/or local legislation.
