Question

Using electron -transfer concept, identify the oxidation and reduction in the following redox reactions.
(a) $$ Zn(s)  + 2H^+(aq) \rightarrow  Zn^{2+}(aq) + H_2(g) $$
(b) $$ 2 [ Fe(CN)_6]^{4-} (aq) + H_2O_2(aq) + 2H^+(aq) \rightarrow 2[Fe(CN)_6]^{3-} (aq) + 2H_2O(aq) $$
(c) $$ 2[Fe(CN)_6]^{3-} (aq) + 2OH^-(aq)  + H_2O_2(aq) \rightarrow 2[Fe(CN)_6]^{4-} (aq)  + 2H_2O(I)$$
(d) $$ BrO^-_3(aq) +F_2(g) +2OH^-(aq) \rightarrow BrO^-_4(aq) + 2F^-(aq) + H_2O(I) $$
(e) $$ 2NaCIO_3(aq)  + I_2(aq) \rightarrow 2NaIO_2(aq) +Cl_2(g) $$


Solution

Oxidants : $$ (a) H^+ (b) H_2O_2 (c) [Fe(CN)_6]^{3-} , (d) Fe , (e) l_2 $$

Reductants : $$ (a) Zn, (b) [Fe(CN)_6]^{4-} , (c) H_2O2 , (d) BrO^-_3 , (e) NaClO_3 $$
