How would you...

Question

How would you account for the increasing oxidising power in the series $V O_{2}^{+} < C r_{2} O_{7}^{2 -} < M n O_{4}^{-}$ ?

Q. How would you account for the following ?

The oxidising power of the following three oxoions in the series follows the order :

V O_{2}^{+} < C r_{2} O_{7}^{2 -} < M n O_{4}^{-}

Q. Which of the following order of oxidising power is correct for the following species?

V O_{2}^{+}, M n O_{4}^{-}, C r_{2} O_{7}^{2 -}

Q. Following order is observed in oxidizing power of certain ions:

V O_{2}^{+}

C r_{2} O_{7}^{2 -}

M n O_{4}^{2 -}

The reason for this increasing order of oxidizing power is:

Q. By how much would the oxidising power of the

(M n O_{4}^{-} | M n^{2 +})

couple change if the

H^{+}

ions concentration is decreased

100

25^{\circ} C

?

H^{+}

concentration is decreased from

1 M

10^{- 4} M

25^{o} C

{M n O_{4}}^{-} / M n^{2 +}

, then the oxidising power of the

{M n O_{4}}^{-} / M n^{2 +}

couple decreases by :
