Question & Answer: The complex [TiCl6]3- has a ligand field splitting of 160. kJ/mol and forms an orange solution……

Color is perceived in two ways i) additive mixing ii) subtractive mixing

i) additive mixing : Color displayed is result of the combination of colors

ii) subtractive mixing : Color displayed is the color whichever is not absorbed

For coordinate complexes subtractive mix8ng is considered

As in our case solution displays Orange color so orange color is not absorbed.

Wavelength of the orange color is around 600 nm , color is orange.
