| Specification: |
?Sodium hydroxide (CAS NO.1310-73-2), also called ?lye and caustic soda, is a caustic metallic base when dissolved in a solvent such as water. It forms a strong alkaline solution, however, only the hydroxide ion is basic. It?should be stored in an airtight container, because it is hygroscopic and readily absorbs carbon dioxide from the air. |
