Answer the following questions for the compound: [Zn(NH3)4]Cl2
What is the coordination number for zinc in the compound?
What is the charge on the complex ion?
What is the oxidation state of the metal?
How many ions are formed when this complex is dissolved in water?
Homework Answers
The complex is [Zn(NH3)4] Cl2
As Zn has 4 NH3 molecules with in the square brackets ( coordination sphere) the coordination number for zinc = 4
the complex ion is the one within the square brackets. It is neutralized with 2 Cl- ions.
Thus the charge on complex ion is +2 .
As the NH3 has no charge and Zn always show +2 , the complex ion is +2 charged. [Zn(NH3)4]+2
[Zn(NH3)4] Cl2 <----------> [Zn(NH3)4] +2 + 2 Cl-
Thus 3 ions are formed when it is dissolved in water.
