Sodium hydroxide (NaOH), also known as caustic soda, is used in industry (mainly as a base chemical) in the manufacture of paper, textiles and detergents. It is also used in cotton textile processing, laundry and bleaching.
IDENTIFICATION AND PROPERTIES
Name: Sodium hydroxide
Synonyms: Caustic Soda, Sodium Hydroxide.
Chemical formula: NaOH
- Appearance: Solid
- Colour: White
- Odour: Odourless
- pH: >13
- Melting point: 318ºC
- Boiling point/boiling range: 1390ºC
- Flammability (solid, gas): Inorganic oxides with the inorganic element in its maximum oxidation state cannot react with further oxygen, therefore they are designated, as non-flammable.
