Sodium Hydroxide/ Caustic Soda


Molecular Formula: NaOH
Molecular Weight: 40.00

CAS No.: 1310-73-2

 

Properties:

White particles or flakes, often made of small flakes. It is easy to absorb water and carbon dioxide in the air. 1g dissolved in 0.9ml cold water, 0.3ml boiling water, 7.2ml ethanol, 4.2ml methanol, soluble in glycerol. When it is dissolved in water or ethanol or when the solution is mixed with acid, it will generate heat. The solution is strongly alkaline. The relative density is 2.13. The melting point is 318 degrees centigrade. The boiling point is 1390 degrees centigrade. Half lethal dose (mice, abdominal cavity) 40mg/kg. It is corrosive. The solution has astringent and greasy feeling. Sodium hydroxide can absorb CO2 and is also a commonly used chemical in biological experiments.
