Predic whichof the followingwillcolouredin aqueoussolutionTi^(2+), V^(3+) Sc^(4+) Cu^(+) ,Sc^(3+) ,Fe^(3+) ,Ni^(2+)and Co^(3+)

Answer»

Solution :(I ) Onlythe ionsthat haveunpairedelectronsin d-orbitaland in whichd- dtransitionis possiblewill becoloured.
(ii) The ionsin whichd - orbitalsareemptyor COMPLETELY filledwill be colourlessas nod-dtransitionis possiblethoseconfiguratin
Fromthe aboveions , it canbe easilyobservedthat only`SC^(3+)`hasan EMPTYD- ORBITAL and `Cu^(+)` hascompletely filledd- orbital.
(iv)All otherions except `Sc^(3+)`and `Cu^(+)`will be COLOURED inaqueoussolutionbecauseofd-d transition.
