Out of `[Sc(H_(2)O)_(6)]^(3+)` and `[Ti(H_(2)O)_(6)]^(3+)`ions which is coloured and why? Give reason.

Explanation

To determine which of the ions \([Sc(H_2O)_6]^{3+}\) or \([Ti(H_2O)_6]^{3+}\) is colored, we need to analyze their electronic configurations and the implications of their oxidation states.

### Step 1: Determine the electronic configuration of Scandium (Sc)
- Scandium has an atomic number of 21. Its ground state electronic configuration is:
\[ [Ar] 3d^1 4s^2 \]
