We know that chromium (III) salts dissolve in water to give violet solution. The violet colour is due to the hydrated chromium (III) in [Cr(H₂O)₆]³⁺.

1. Ti (22) = [Ar]3d²4s² minimum oxidation state is +2 and maximum oxidation state is +4.
2. Ti⁴⁺ = [Ar]; Ti³⁺ = [Ar]3d¹; Ti²⁺ = [Ar]3d². Hence, it is most stable state of Ti.
3. It acts as a good reducing agent as it can readily oxidized to Ti⁴⁺ ion.
4. It is the most unstable form. Thus, +3 and +4 are the common oxidation states.

Correct answer: It acts as a good reducing agent as it can readily oxidized to Ti⁴⁺ ion.

Solution

Option C is correct because Ti²⁺ acts as a good reducing agent due to its ability to be oxidized to the more stable Ti⁴⁺ state. This is consistent with the electronic configuration and stability trends of titanium ions.
