Ammonia nitrogen is present in a given waste water sample as the ammonium ion  and ammonia 3
(NH3). If pH is the only deciding factor for the proportion of these two constituents, which of the following is correct statement? 
  • a)
    At pH below 9.25, NH3 will be predominant 
  • b)
    At pH = 7,  and NH3 will be found in equal measures.  
  • c)
    At pH = 7,  will be predominant.  
  • d)
    At pH above 9.25, only  will be present. 
Correct answer is option 'C'. Can you explain this answer?

Ammonia exist in the form of & NH3
  • At pH < 8, all ammonia is in the form of
  • At pH = 9.5, there are 50% NH3 & 50%
  • At pH > 11, all ammonia is in the form of NH3  
Hence, option (C) is correct that at pH = 7, + will be predominant.  
Hence, the correct option is (C).
