Write Four Properties Of Nitric Acid

Nitric Acid is a highly corrosive mineral acid. The pure compound is colourless, but older samples tend to acquire a yellow cast due to decomposition into oxides of nitrogen and water. The properties of Nitric Acid are given below.

  • Its freezing point is 231.4K whereas its boiling point is 355.6 K. It has a colourless appearance.
  • Conc. nitric acid is a strong oxidizing agent. It can oxidize most metals (it cannot oxidize noble metals like Pt)
  • Concentrated nitric acid can also be used to oxidize non-metals. E.g. nitric acid can oxidize iodine to iodic acid.
  • An aqueous solution of nitric acid is strongly acidic since it can give both hydronium and nitrate ions.
