Statement 1: Ti (III) salts are coloured whereas Ti (IV) salts are white.Statement 2: Ti (III) is less stable than Ti (IV).

Correct explanation: Ti (III) salts have one unpaired electron in d-subshell (3d1) whereas Ti(IV) salts no electron in the d-subshell (3d0).Ti(IV) is the nearly inert gas configuration so Ti(IV) salts are more stable
