Vedclass · Answer

(D) The acidic or basic nature of transition metal oxides depends on the oxidation state of the metal. Generally,oxides of transition metals in lower oxidation states are basic,while those in higher oxidation states are acidic or amphoteric. Let us calculate the oxidation states of the metals in the given oxides: $Cr_2O_3$: $2x + 3(-2) = 0 \implies x = +3$ (Amphoteric) $CrO_3$: $x + 3(-2) = 0 \implies x = +6$ (Acidic) $V_2O_5$: $2x + 5(-2) = 0 \implies x = +5$ (Acidic) $V_2O_3$: $2x + 3(-2) = 0 \implies x = +3$ (Basic) Among the given options,$V_2O_3$ has the metal in a lower oxidation state compared to the others,making it the most basic oxide.
