`Cr_(2)O_(7)^(2-)overset(H^(+))rarrCr^(3+)`, Eq. wt. of `Cr_(2)O_(7)^(2-)` is :-A. mol. Wt/6B. mol. Wt/3C. mol. Wt/4D. mol. Wt/1

Answer» Correct Answer - A
Reduction of `Cr_(2)O_(7)^(2-)` to `Cr^(3+)` is `6e^(-)` change
`Cr_(2)O_(7)^(2-)+14H^(+)+6e^(-)rarr2Cr^(3+)+7H_(2)O`
`:.` Eq. wt of `Cr_(2)O_(7)^(2-) =` Mol. Wt/6.
