  • Hydrogen Chloride has molecular formula HCl and molecular mass of 36.5. 
    When hydrogen chloride gas is dissolved in water, hydrochloric acid is formed.
  • Ammonia has molecular formula NH3 and molecular mass of 17.
    The pungent smell which is encountered near a decaying heap of organic matter is due to ammonia. It is produced due to bacterial decomposition of urea.
  • Nitric Acid has molecular formula HNO3 and molecular mass 63.
    This acid was formerly known as aqua fortis meaning strong water because it reacts with nearly all metals. It can also dissolve silver which is not dissolved in any other acid.
  • Sulphuric Acid has molecular formula H2SO4 and molecular mass of 98.
    Sulphuric acid is called 'King of Chemicals' because of its extensive use in large number of industries.

           Learn more about the occurrence, preparation, properties and uses of hydrogen chloride, nitric acid, sulphuric acid and ammonia in this module.
