Does Pt(NH3)2Cl2 conduct electricity?
Pt(NH3)2Cl2 does not conduct electricity in its solid state. This is because it is a coordination compound that consists of a central metal ion (platinum) surrounded by ligands (ammonia and chloride ions). In its solid form, the compound does not have any mobile charge carriers that can carry an electric current.
However, when Pt(NH3)2Cl2 is dissolved in water or any other solvent, it can conduct electricity. This is because the compound dissociates into its ions in solution, leading to the formation of mobile charge carriers. The ammonia ligands coordinate with the platinum ion, forming a complex cation, [Pt(NH3)2]^2+, while the chloride ions become free anions. These ions can move freely in the solution and carry an electric current.

Explanation:
- In solid state: Pt(NH3)2Cl2 does not conduct electricity due to the lack of mobile charge carriers.
- In solution: Dissolved Pt(NH3)2Cl2 dissociates into ions, allowing it to conduct electricity.
- Mobile charge carriers: The complex cation [Pt(NH3)2]^2+ and free chloride anions enable the conduction of electricity.
In conclusion, Pt(NH3)2Cl2 can conduct electricity when dissolved in a solvent, but not in its solid state. This difference in behavior is due to the presence of mobile ions in the solution, which can carry an electric current.
