About Sodium Hydroxide: Chemical and Physical Properties

  • Alternative names: caustic soda, lye
  • Molecular formula: NaOH
  • Molecular weight: 39.99 g/mol
  • Appearance: can be sold as crystals, flakes, beads, pellets, powder or in solution
  • Colour: colourless to white
  • Odour: odourless
  • Boiling point: 1388 degree Celsius (2534 Fahrenheit)
  • Melting point: 318 degree Celsius (605 Fahrenheit)
  • Solubility: can dissolve in alcohol, glycerol and water
  • Density: 2.13 g/cu (25 degree Celsius)
  • Stability: sodium hydroxide needs to be stored in a tightly closed container, to prevent exposure to carbon dioxide, which converts this compound to sodium carbonate. Sodium hydroxide is known for its ability to rapidly absorb carbon dioxide from water and air
  • Decomposition: It may release toxic fumes and gases when heated
  • Corrosivity: highly corrosive to certain metals and glass
  • pH: alkaline solution, ranging from pH 12 (0.05% w/w solution) to 14 (5% w/w solution)
  • Reactivity: sodium hydroxide can react with mineral acids, forming the respective salt. It can also react with weak acids, including sulphur dioxide and hydrogen sulphide and carbon dioxide, as well as amphoteric metals (such as zinc and aluminium) and their oxides, to generate complex anions. Lastly, organic acids also react with this compound to produce soluble salts.
  • Storage: This compound can be very dangerous, and safe storage is essential to ensure staff safety. Sodium hydroxide must be stored away from acids and metals, in its original containers and tightly closed
