Identify cationic sphere complex from following.
  1. Tetraaminecopper(II) ion
  2. Tetracyanonickelate(II) ion
  3. Trioxalatocobaltate(III) ion
  4. Triamminetrinitrocobalt(III)

Solution

Tetraaminecopper(II) ion : $\left[\mathrm{Cu}\left(\mathrm{NH}_3\right)_4\right]^{2+}$ Tetracyanonickelate(II) ion : $\left[\mathrm{Ni}(\mathrm{CN})_4\right]^{2-}$ Trioxalatocobaltate(III) ion : $\left[\mathrm{Co}\left(\mathrm{C}_2 \mathrm{O}_4\right)_3\right]^{3-}$ Triamminetrinitrocobalt(III) : $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_3\left(\mathrm{NO}_2\right)_3\right]$ Tetraaminecopper(II) ion is a cationic sphere complex.
