Answer : The overall charge on the complex is, (-2)
Explanation :
The given coordination complex is, hexachloroplatinate(IV)
The formula of the given coordination complex is represented as,
![[Pt(Cl)_6]^(x)](https://img.qammunity.org/2019/formulas/chemistry/college/l52pm90h4wmnsmpyn5tq375u1zmnmyziaw.png)
Now we have to calculate the overall charge (x) on the complex.
The oxidation sate of Pt = +4 (given)
The charge on one chloro = -1
x = (+4) + 6(-1) = -2
The formula of the given coordination complex is represented as,
![[Pt(Cl)_6]^(-2)](https://img.qammunity.org/2019/formulas/chemistry/college/h4781tdh35um0bthxhmyrtij7yl6ejoxfq.png)
Therefore, the overall charge on the given complex is, (-2)
