A complex compound of \(\mathrm{Co}^{3+}\) with molecular formula \(\mathrm{CoCl}_{\mathrm{x}} \cdot \mathrm{yNH}_3\) gives a total of 3 ions when dissolved in water. How many \(\mathrm{Cl}^{-}\)ions satisfy both primary and secondary valencies in this complex?
- A 3
- B 1
- C 4
- D zero
Answer & Solution
Correct Answer
(B) 1
Step-by-step Solution
Detailed explanation
As cobalt is present as \(\mathrm{Co}^{3+}\) and co-ordination number of cobalt is 6 , the molecular formula of compound should be \(\mathrm{CoCl}_3 \cdot \mathrm{yNH}_3\). Now, as it gives a total of 3 ions when dissolved in water, its structural formula must be…
