Hi I have a question:
The two complexes [NI(OH2)2]2+ and [Ni(NH3)]2+
are both colored. One is green, the other is blue. Which is which?
Ok, so both complexes are octahedral and d8.
[NI(OH2)2]2+ is high spin and weak field.
[Ni(NH3)]2+ is strong field ligand = low spin.
How from this information distinguish colors?
