Identify anionic sphere complex from following.

Identify anionic sphere complex from following.
  1. Hexaamminecobalt(III) chloride
  2. Potassium hexacyanoferrate(II)
  3. Tetraamminedichlorocobalt(III) ion
  4. Pentaamminechlorocobalt(III) sulphate

Solution

(A)$\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_6\right] \mathrm{Cl}_3 \Rightarrow$ Cationic sphere complex (B)$\mathrm{K}_4\left[\mathrm{Fe}(\mathrm{CN})_6\right] \Rightarrow$ Anionic sphere complex (C)$\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_4 \mathrm{Cl}_2\right]^{+} \Rightarrow$ Cationic sphere complex (D)$\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_5 \mathrm{Cl}\right] \mathrm{SO}_4 \Rightarrow$ Cationic sphere complex
