Sodium hydroxide (previously called caustic soda, caustic soda), NaOH, belongs to strongest principles. It is a highly hygroscopic, in normal conditions is a white solid substance, corrosive skin. This is an inorganic substance. In aqueous solution acts as a strong base. It absorbs carbon dioxide from the air, forming sodium carbonate and therefore must be stored in airtight containers. Global production in 1998 was about 45 million tons. The melts hydroxide is one of the few materials which etch silica, react with it quite intensively.
