from KCr(SO4)2.12H2O(s) pale purple. (heat green). Due to impurities, it is common for Cr(III) to appear green in solution. Cr(OH)3(s). |
Colour arises in transition metals because they have part filled d sub orbitals. In a transition metal atom, all the d orbitals have the same energy. |
Complex ions containing transition metals are usually coloured, whereas the similar ions from non-transition metals aren't. That suggests that the partly filled ... |
