13 Uses of Sodium Hydroxide (NaOH) One Should Know
Would you like to know about Sodium Hydroxide, one of the most widely used chemicals in the world?Have you ever wondered what is the most important ingredient in making soaps and other detergents that we use for cleaning? You may be wondering how a chemical can be so corrosive as well as so usable.. If you want to know all information then you have come to the right place. Sodium hydroxide is generally known as caustic soda and the less common name of sodium hydroxide is lye. It is a water-soluble strong base used in several manufacturing processes. The solution of sodium hydroxide is considered a strong base. Although in many industrial areas such as paper or chemical industries it is used as a universal neutralizing agent. Sodium hydroxide with the formula of NaOH consists of anion OH– and cation Na+. At room temperature appears as a white crystalline odorless solid that may be in the form of pellets, granules, or powder. Stay with us so we can tell you more about this usable chemical.
Properties of Sodium Hydroxide (NaOH)
In order to describe its uses, it is necessary to describe the features that caustic soda is used in a variety of industries due to these chemical and physical features.
1: An ionic bond is present between sodium ion (Na+) and hydroxide ion (OH–).
2：An oxygen and Hydrogen atom of hydroxide ion (OH–) binds by a covalent bond.
3：As NaOH is a strong base, Salts and water are formed by reaction with protic acids. It is an exothermic reaction that releases a large amount of heat due to hydrate formation.
Antioxidants: In Depth
Antioxidants are man-made or natural substances that may prevent or delay some types of cell damage. Diets high in vegetables and fruits, which are good sources of antioxidants, have been found to be healthy; however, research has not shown antioxidant supplements to be beneficial in preventing diseases. Examples of antioxidants include vitamins C and E, selenium, and carotenoids, such as beta-carotene, lycopene, lutein, and zeaxanthin. This fact sheet provides basic information about antioxidants, summarizes what the science says about antioxidants and health, and suggests sources for additional information.
Key Points
Vegetables and fruits are rich sources of antioxidants. There is good evidence that eating a diet that includes plenty of vegetables and fruits is healthy, and official U.S. Government policy urges people to eat more of these foods. Research has shown that people who eat more vegetables and fruits have lower risks of several diseases; however, it is not clear whether these results are related to the amount of antioxidants in vegetables and fruits, to other components of these foods, to other factors in people’s diets, or to other lifestyle choices.
Rigorous scientific studies involving more than 100,000 people combined have tested whether antioxidant supplements can help prevent chronic diseases, such as cardiovascular diseases, cancer, and cataracts. In most instances, antioxidants did not reduce the risks of developing these diseases.
Concerns have not been raised about the safety of antioxidants in food. However, high-dose supplements of antioxidants may be linked to health risks in some cases. Supplementing with high doses of beta-carotene may increase the risk of lung cancer in smokers. Supplementing with high doses of vitamin E may increase risks of prostate cancer and one type of stroke.
Antioxidant supplements may interact with some medicines.

Sodium hydroxide – cleaning, sanitization agent in chromatography media and columns
Sodium Hydroxide Solution is the principal strong base used in the chemical industry. In bulk it is most often handled as an aqueous solution, since solutions are cheaper and easier to handle. Sodium hydroxide is also used for the manufacture of sodium salts and detergents, for pH regulation, and for organic synthesis. Sodium hydroxide is employed to digest tissues, such as in a process that was used with farm animals at one time. This process involved placing a carcass into a sealed chamber, then adding a mixture of sodium hydroxide and water. This eventually turns the body into a liquid with coffee-like appearance and the only solid that remains are bone hulls, which could be crushed between one's fingertips. It is common practice in industrial manufacturing to save time by adding a salt, such as sodium chloride, to the sodium hydroxide solution to combine cleaning with sanitization.
During restrictive inspections, producers of biopharmaceuticals and biological products usually give attention to cleaning and cleaning validation of chromatography resins and multiuse purification systems. Chromatographic resins must either be disposed of or sufficiently cleaned to ensure reproducibility in subsequent cycles.
SODIUM HYDROXIDE 99% FOOD GRADE FOR SOAP MAKING
Sodium hydroxide 99% is a white, odorless, nonvolatile alkaline material marketed in solid form as pellets, flakes, clumps, or sticks. Its solubility in water is 111% by weight and a vapor pressure of 0mmHg (NIOSH, 1994). It can react with tricholoethylene (TCE) to form flammable dichloroacetylene and with metals to form hydrogen gas (OEHHA, 1993). Its reactivity with metals should be considered in regards to storage units and containers.
What are Caustic Soda Pearls?
Caustic Soda Pearls Specification (also known as sodium hydroxide, caustic soda, NaOH, sodium hydrate, or Sodagrain) are white spheres of caustic soda with a barely perceptible odour. They are soluble in water, with the liberation of heat, and are stable under normal conditions. Caustic soda is a strong base and, as such, has many applications in industries all over the world, both now and in the past. It is one of the oldest manmade chemicals with excavations in Egypt showing samples of it dating from 3000 B.C.
How are Caustic Soda Pearls produced?
Caustic soda is produced all around the globe with world production standing at approximately 59 million tonnes per annum (in 2008). Virtually all producers use the chloralkali process which involves the electrolysis of sodium chloride using one of three cell types: mercury, diaphragm, or membrane. If this process is used, 1.1 tonnes of caustic soda can be produced to each tonne of chlorine.
How are Caustic Soda Pearls stored and distributed?
Caustic soda pearls are stored and transported in 25 kg woven bags with a PE liner. For transportation purposes they are classed as packing group II, hazard class 8 and they are corrosive and can cause burns. They have a specific gravity of 2.13.
What are Caustic Soda Pearls used for?
Caustic soda pearls are an important inorganic chemical as they are used in numerous industries worldwide. The highest demand for caustic soda comes from the paper industry where it is utilised in pulping and bleaching processes. They are also in demand in the aluminium industry as the caustic soda dissolves bauxite ore, which is the raw material in aluminium production. Another major use for caustic soda is chemical processing as caustic soda is a basic feedstock for a range of down-stream products including solvents, plastics, fabrics, adhesives etc. Caustic soda pearls are also used in soap production as they engender saponification of the vegetable oils or fats that are necessary for soap manufacture. They have a role in the natural gas industry where sodium hydroxide is used to help produce and process petroleum products and they can be employed in the textile industry where it is used in the chemical processing of cotton. Caustic soda also has small scale applications. It can be used for aluminium etching, chemical analysis and in paint stripper. It is a component in a range of domestic products including pipe and drain cleaner, oven cleaner and in home-cleaning products.
