CuSO₄ dissolves in NH₃ due to the formation of
Options
(a) Cu(OH)₂
(b) Cu[(NH₃)₄]SO₄
(c) Cu[(NH₃)₄(OH)₂]
(d) CuO
Correct Answer:
Cu[(NH₃)₄(OH)₂]
Explanation:
NH₃+ H₂O→ NH₄OH
CuSO₄ + NH₄OH → Cu(OH)₂ + (NH₄)₂ SO₄ / Cu(OH)₂ + 2NH₄OH + (NH₄)₂ SO₄ → [Cu (NH₂)₄] SO₄ + 4 H₂O ( Tetrammine cupric sulphate
The complex is called as Schotzer’s reagent which is used for dissolving cellulose in the manufacture of artificial silk.
