Ammonia forms the complex ion [Cu(NFl3)4]2+ with copper ions in the alkaline solutions but not in acidic solutions. What is the reason for it?
(AIEEE 2003)
  • a)
    In acidic solutions, hydration protects copper ions
  • b)
    In acidic solutions, protons coordinate with ammonia molecules forming NH4+ ions and NHmolecules are not available
  • c)
    In alkaline solutions ,insoluble Cu(OH)2 is precipitated which is soluble in excess of any alkali
  • d)
    Copper hydroxide is an amphoteric substance
Correct answer is option 'B'. Can you explain this answer?

Ammonia forms the complex ion [Cu(NFl3)4]2+ with copper ions in the al...
In acidic solutions, N-atoms of NH3 donates their lone pair electrons to protons forming NH4+ ions.
Therefore, lone pair electrons of NH3 are not available for forming the complex with copper ions.
