Inorganic Chemistry MCQ with Answers

216) NH₃ forms complex ion [Cu(NH₃)₄]SO₄ with CuSO₄ in alkaline solution, but not in acidic solution because:

Cu²⁺ is hydrated in acidic medium

Cu(OH)₂ is formed in alkaline solution which dissolves in NH₃ (excess)

NH₃ is protonated to form NH₄⁺ in acidic medium, therefore, pair of electrons is no more available for coordination

Cu(OH)₂ is amphoteric

Answer is:

NH₃ is protonated to form NH₄⁺ in acidic medium, therefore, pair of electrons is no more available for coordination
