Question

Why removal of water from [Ti(H2O)6] Cl3 on heating renders it colourless?

Answer 1

Answer:

Explanation:

• The colour is due to the transition of e - from t2g to eg orbital. the d-orbitals splitting takes place when the ligands are there.
• Heating removes the water molecule from the coordination sphere.colour and magnetism of transition compounds mainly arises due to d electrons in transition metal ion-Sc+3 has no d electrons
• Ti (H2O)6 +3 is purple in colour .
• titanium dioxide more commonly called Ti(IV) oxide is white and has use in pigments paper, .paints.
• in d block transition elements Sc is first and Ti is second
• Ti(H20)63+ is purple in solution. ... The chemistry of scandium strongly resembles that of the lanthanides, with most of its compounds being colorless and diamagnetic. ... The water of hydration is driven off by heating to form pure Ti02: Ti02 • H20(s) Ti02(s) + H20(g) In its compounds, titanium is most often found in the +4 ...
• THE COLOUR IS DUE TO TRANSITION OF e_ from T2g to Eg orbital.
• the d orbitals spliting takes place when the ligands are there
• heating removes water molecule from the coordination sphere.
• as a result there is no crystal field spliting hence no colour is observed
