WebIn case of [Fe (CN) 6] 4− and [Fe (H 2 O) 6] 2+, the colour differs because there is a difference in the CFSE. Now, CN − is a strong field ligand having a higher CFSE value as compared to the CFSE value of water. This means that the absorption of energy for the intra d-d transition also differs. Hence, the transmitted colour also differs. morning or evening exercise for weight loss
