Answer:
Sodium hydroxide is corrosive to all body tissues; concentrated vapors cause serious damage to the eyes and respiratory system. Ingestion of sodium hydroxide, which occurs frequently in children, can cause severe necrosis, with stricture of the esophagus and death.

Sodium hydroxide can be used to react with a nonmetal oxide, which is a compound that contains a nonmetal like carbon or sulfur bonded with oxygen. Sodium hydroxide reacts with the nonmetal oxide to produce an ionic compound and water.
