Sodium hydroxide

Dataset description

Sodium hydroxide (NaOH), also known as caustic soda or lye, is a corrosive white crystalline solid that contains the sodium cation and the hydroxide anion. It readily absorbs moisture until it dissolves. It is the most widely used industrial alkali and is often used in drain and oven cleaners. Sodium hydroxide is a co-product of chlorine production. It is a highly versatile substance used in a variety of manufacturing processes. In 1807, Sir Humphry Davy became the first to prepare sodium in its elemental form, applying electrolysis to fused sodium hydroxide.
