Potassium dichromate is an orange colour crystal and is an important compound used as an oxidant in many reactions How will you account for the colour of potassium dichromate crystals? |
| Answer» Solution :Orange colour of dichromate ion and potassium dichromate is DUE to charge transfer (i.e., momentary transfer of charge from oxygen to metal). It is not,due to d-d transition because `CR^(+6)` does not CONTAIN any ELECTRON in tZ-orbital. | |
