coulour of transition elements Watch
Hi i am a little stuck an how to work out the colour of a transition element from its absorbtion spectrum. ive got a past paper question and the main absorbance is just below 500nm where do i go from there?
As your compound absorbs below 500nm, ie the blue end of the spectrum, it will appear red/orange as these are the colours that are not absorbed.
Just remove the colours that are absorbed and make a guess at a colour from what is left! (in the end they should accept a range of colours in the markscheme).

check this out. White light is made up of three colours. Absorb one and you are left with the mix of the other two.
eg: absorb red and you are left with the sum of the blue and the green = cyan
