Caustic Soda Pearls

Sodium hydroxide, also known as caustic soda and caustic potash, with the chemical formula NaOH, is a highly corrosive strong base. It typically appears as white flakes or particles and is miscible with water to form an alkaline solution. Additionally, it can dissolve in methanol and ethanol. This alkaline substance is deliquescent, absorbing water vapor from the air and also absorbing acidic gases such as carbon dioxide. Sodium hydroxide is one of the commonly used chemicals.
