What is the chemical formula of sodium hydroxide and what are its uses?

The chemical formula of sodium hydroxide is NaOH, and it is widely used as a strong base in industries and laboratories.

NaOH, also called caustic soda, is a white solid that dissolves in water releasing heat. It is used in making soaps, detergents, paper, and textiles. It also neutralizes acids and helps clean surfaces by breaking down grease. 

In labs, it serves as a reagent in acid-base titrations. In water treatment, NaOH adjusts pH levels, and in food processing, it softens olives and helps remove skins from fruits. Its corrosive nature requires careful handling with gloves and goggles.
