Vedclass · Answer

(C) $K_{2}Cr_{2}O_{7}$ is a strong oxidizing agent used in redox titrations. It is prepared from $K_{2}CrO_{4}$ by adding acid. It is orange in color. However,it is not stable in both acid and base; it exists as $Cr_{2}O_{7}^{2-}$ (dichromate) in acidic medium and converts to $CrO_{4}^{2-}$ (chromate) in basic medium. Thus,the statement that it is stable in both acid and base is incorrect.
