Sapling HW 9 Problem #6

[Adam_Ventura_1H]

For this question I am supposed to give the oxidative state of [Co (NH3)5 Cl] Cl. My question is, when trying to find the oxidative state, do we have to look at everything that has a charge, whether it is inside or outside? For example, do I take into account the Cl outside of the brackets or not?

[Joseph Hsing 2C]

Yup for oxidative number, we take into account the atoms and ions inside and outside of the coordination sphere.

[Savana Maxfield 3F]

Yeah! So basically, since this is a coordination compound and coordination compounds have a neutral charge, you need to use information both inside and outside of the brackets in order to ensure that the overall charge of the compound in zero! Since Cl has a -1 charge, make sure that the overall charge of what is contained within the brackets, [Co (NH3)5 Cl], is +1 to result in an overall charge of the compound equal to 0! Hope this helps :)

Yes, you would have two take into account the Cl outside of the brackets. In this problem, the oxidative state of [Co (NH3)5 Cl] Cl will be 3+
