Which of the following gives the maximum number of ions in aqueous solution?

  1. A \(\mathrm{Ni}(\mathrm{CO})_4\)
  2. B \(\mathrm{CoCl}_3 \cdot 5 \mathrm{H}_2 \mathrm{O}\)
  3. C \(\mathrm{PtCl}_4 \cdot 6 \mathrm{NH}_3\)
  4. D \(\left[\mathrm{Cr}\left(\mathrm{NH}_3\right)_3 \cdot\left(\mathrm{NO}_2\right)_3\right]\)
Verified Solution

Answer & Solution

Correct Answer

(C) \(\mathrm{PtCl}_4 \cdot 6 \mathrm{NH}_3\)

Step-by-step Solution

Detailed explanation

\(\mathrm{PtCl}_4 \cdot 6 \mathrm{NH}_3\) [hexammine platinum (IV) chloride]. It gives \(4 \mathrm{Cl}^{-}\)ions and \(6 \mathrm{NH}_3\), not involved in its ion because \(\mathrm{NH}_3\) are present out of the complex of \(\mathrm{PtCl}_4\).…
