Caustic soda is the most typical of the strong alkalis. Although there is no danger of it exploding or igniting, it reacts with various acids, such as hydrochloric acid, and is neutralized and generates considerable exothermic heat of neutralization.
1. It corrodes metals, such as aluminum, tin, and zinc. During this process, it generates hydrogen, which has the potential to behave as an explosive gas.
2. It is highly hygroscopic, and absorbs the moisture, carbon dioxide, or sulfur dioxide in the air. It is also highly deliquescent and absorbs moisture to form an aqueous solution.
3. When liquid caustic soda is diluted, it generates a considerable amount of heat of dilution. Since this rapidly generates strong heat and the resulting solution may spatter if the water is carelessly poured into it, care must be taken.
4. Caustic soda easily decomposes animal fibers. Although plant fibers are also decomposed, they have a higher resistance than animal fibers. Although materials resistant to corrosion by caustic soda include stainless steel, steel-epoxy resins, and fiber-reinforced plastics, steel and rubber-lined steel are the most frequently used.
