Question

Using electron -transfer concept, identify the oxidation and reduction in the following redox reactions.
(a) $Z n (s) + 2 H^{+} (a q) \to Z n^{2 +} (a q) + H_{2} (g)$
(b) $2 [F e (C N)_{6}]^{4 -} (a q) + H_{2} O_{2} (a q) + 2 H^{+} (a q) \to 2 [F e (C N)_{6}]^{3 -} (a q) + 2 H_{2} O (a q)$
(c) $2 [F e (C N)_{6}]^{3 -} (a q) + 2 O H^{-} (a q) + H_{2} O_{2} (a q) \to 2 [F e (C N)_{6}]^{4 -} (a q) + 2 H_{2} O (I)$
(d) $B r O_{3}^{-} (a q) + F_{2} (g) + 2 O H^{-} (a q) \to B r O_{4}^{-} (a q) + 2 F^{-} (a q) + H_{2} O (I)$
(e) $2 N a C I O_{3} (a q) + I_{2} (a q) \to 2 N a I O_{2} (a q) + C l_{2} (g)$
