1.Product Property
Sodium hydroxide, also known as caustic soda and lye, has the chemical formula NaOH. It is a highly corrosive strong base. It is usually in the form of white tablets or granules and can dissolve in water to form an alkaline solution. It can also dissolve in methanol and ethanol. This alkaline substance has hygroscopic properties and absorbs water vapor from the air, as well as absorbs acidic gases such as carbon dioxide. Sodium hydroxide is one of the commonly used chemicals. It is widely applied and is a necessary substance in many industrial processes.
