Practising drawing complex ions from www.ChemistryTuition.Net

The whole charge out the bracket [Cr(nh3)⁶]+3 (e.g+3 ) is it oxidation state

[azww]

for the square planar example. how do you know if its cis- or trans- configuration or is there a resonance structure equivalent for complex ions?
thank you.

How is the oxidation number of co +3 because cl is -2 in bracket all together then if you + 1 you get -1 ???

[atiarimi]

For the first example how do you know that the charge on the Cr is 3+ ?

I wonder how the girls ended up doing 😂
