Answer»

Balance the following redox reactions by ion-electron method:
$M n O_{4}^{-} (a q) + I^{-} (a q) \to M n O_{2} (s) + I_{2} (s)$ (in basic medium)

$M n O_{4}^{-} (a q) + S O_{2} (g) \to M n^{2 +} (a q) + (a q) H S O_{4 (a q)}^{-}$ (in acidic solution)

$H_{2} O_{2} (a q) + F e^{2 +} (a q) \to F e^{3 +} (a q) + H_{2} O (l)$ (in acidic solution)

$C r_{2} O_{7}^{2 -} + S O_{2} (g) \to C r^{3 +} (a q) + S O_{4}^{2 -}$ (aq) (in acidic solution)
