Sodium hydroxide, also known as Caustic Soda or lye, is a white solid and highly caustic metallic base and alkali salt. It is a commercially available product with CAS number 7647-10-1.

Sodium hydroxide is a strong base and readily absorbs moisture and carbon dioxide from the atmosphere. It has a wide range of applications in the chemical industry, including in the manufacture of soaps, detergents, paper, textiles, and other products. It is also used in metal finishing, food processing, water treatment, and oil refining.

At room temperature, Sodium hydroxide is a white crystalline solid with no odor. It is soluble in water and forms a clear, colorless solution. In solution, it is highly alkaline, with a pH of about 13. It is strongly corrosive, and contact with skin or eyes can cause caustic burns as it reacts with proteins.

Sodium hydroxide is also used in the synthesis of active pharmaceutical ingredients and as a reagent in analytical chemistry. It is an important raw material in several chemical industries and is used as an electrolyte in alkaline batteries.

Sodium hydroxide is classified as corrosive and should be handled with caution. It should be stored in a cool, dry and well-ventilated area away from heat and direct sunlight. When handling this substance, protective clothing and safety goggles should be worn.
