Sodium hydroxide (Cat No.:R030463), also known as caustic soda or lye, is a highly caustic, white, odorless solid commonly available in pellets, flakes, or solutions. It is a strong base widely used in industries for pH regulation, chemical manufacturing, soap production, and water treatment. In laboratories, it’s a key reagent in titrations and organic synthesis. Sodium hydroxide reacts exothermically with water and can cause severe chemical burns, so careful handling is essential. Its ability to break down organic matter also makes it useful in drain cleaners and industrial degreasing applications.
