NaOH

Sodium hydroxide (NaOH) is a highly caustic and reactive inorganic compound commonly referred to as lye or caustic soda. It is a white solid with a crystalline appearance and often appears as small pellets, flakes, or granules.

Sodium hydroxide is widely used in various industries, including paper and pulp production, textiles, soap and detergent manufacturing, water treatment, and food processing. It is also used in the production of various chemicals, such as sodium silicates, sodium borohydride, sodium phenolate, and others.

One of the key properties of sodium hydroxide is its high alkalinity, which makes it a strong base that can elevate the pH of solutions and react with acidic compounds. It is highly soluble in water and can react exothermically with water to produce heat.

Sodium hydroxide is also a corrosive substance that can cause severe burns and is hazardous to handle without proper precautions. It should be stored in a cool, dry place, and workers handling it should wear appropriate protective equipment, such as gloves, goggles, and respirators.

Overall, sodium hydroxide is a versatile and essential chemical that plays a vital role in numerous industrial processes. However, it is crucial to handle it with care and follow all recommended safety procedures to prevent accidents and minimize potential harm to workers and the environment.
