Explanation:
Complex compound information:
- Molecular formula: CoClxyNH
- Total ions per molecule when dissolved in water: 3
Analysis:
- Since the complex has a total of 3 ions per molecule, it must have a coordination number of 3.
- The coordination number is equal to the number of ligands attached to the central metal ion.
- In the given complex, the ligands are Cl and NH3.
- The primary valency of Co2+ is 3, which is satisfied by Cl- ions.
- The secondary valency of Co2+ is also 3, which is satisfied by NH3 ligands.
Number of Cl ions satisfying primary valencies:
- Since the primary valency of Co2+ is 3, the number of Cl ions satisfying primary valencies in the complex is 1.
- Therefore, the correct answer is option C (1).
This explanation clarifies that only 1 Cl ion satisfies the primary valency in the complex compound CoClxyNH.
