Identify neutral sphere complex from following.

Identify neutral sphere complex from following.
  1. Pentaamminecobalt(III) sulphate
  2. Potassiumtrioxalatoaluminate(III)
  3. Diamminedichloroplatinum(II)
  4. Potassiumhexacyanoferrate(III)

Solution

The complexes in which the coordination sphere does not carry any charge are called neutral complexes. Diamminedichloroplatinum(II): $\left[\mathrm{Pt}\left(\mathrm{NH}_3\right)_2 \mathrm{Cl}_2\right]$ is a neutral complex. Pentamminecobalt(III) sulphate is a cationic complex, Potassiumhexacyanoferrate(II) and Potassium trioxalatoaluminate(III) are anionic complexes.
