Answer» ❇️MARK AS BRAINLIST PLZ❇️❣️❣️❣️❣️❣️❣️❣️❣️❣️❣️❣️❇️The complementary COLOUR is TRANSMITTED which is violet. The colour due to this transition is CALLED d-d transition. In the absence of ligands, crystal field splitting does not occur, colour DISAPPEARS. Hence, anhydrous TiCl3 is colourless, but Ti(H2O)6Cl3 is violet.❇️
