Seforms colourless salts. Explain. |

Answer» It's because Sc3+ does not have any electrons left in its d orbital. Sc has the electron configuration [Ar](4s)2(3d)1 but in order to get its +3 oxidation state, it has to lose 3 electrons, starting with the two 4s electrons and followed by the lone 3d electron. Sonce there are no more d electrons, electronic transitions are not gonna happen at the visible range of the electromagnetic radiation hence Sc3+ appears colorless. |
