The conversion of to is: — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

In $Cr_2O_7^{2-}$, $Cr$ is $+6$. In $CrO_4^{2-}$, $Cr$ is also $+6$. This reaction is usually driven by a change in pH (alkaline medium) and involves no change in oxidation state. [1, 2]
