Vedclass · Answer

(A) $1$. Identification of acidic oxides:$CrO_3$ and $Mn_2O_7$ are acidic oxides.$VO_2$ is amphoteric,$V_2O_3$ is basic,and $V_2O_5$ is amphoteric.Therefore,$X = 2$.$2$. Determination of primary valency:In the complex $[Co(en)_3]_2(SO_4)_3$,the coordination entity is $[Co(en)_3]^{3+}$.The oxidation state of $Co$ is $+3$,which represents its primary valency.Therefore,$Y = 3$.$3$. Calculation:$X + Y = 2 + 3 = 5$.

$X$ is the number of acidic oxides among $VO_2$,$V_2O_3$,$CrO_3$,$V_2O_5$ and $Mn_2O_7$. The primary valency of cobalt in $[Co(en)_3]_2(SO_4)_3$ is $Y$. The value of $X+Y$ is $:$
