Vedclass · Answer

(A) $I$. $V^{2+}$ is violet,$Cr^{3+}$ is violet,and $Mn^{3+}$ is violet. All three ions exhibit a violet colour in aqueous solution.$II$. $Zn^{2+}$ is colourless,$V^{3+}$ is green,and $Fe^{3+}$ is yellow.$III$. $Ti^{4+}$ is colourless,$V^{4+}$ is blue,and $Mn^{2+}$ is pink.$IV$. $Sc^{3+}$ is colourless,$Ti^{3+}$ is purple,and $Cr^{2+}$ is blue.Therefore,the set with the same colour is $V^{2+}, Cr^{3+}, Mn^{3+}$.

The correct set of ions (aqueous solution) with the same colour from the following is:
