Using electron transfer concept identify the oxidant and redcutant in the following redox reaction
(a) `Zn(s)+2H^(+)(sq)rarrZn^(2)(aq)+H_(2)(g)`
(b)`2[Fe(CN_(3))]^(4-)(aq)+H_(2)O_(2)(aq)+2H^(+)(aq)rarr 2[Fe(CN)_(6)]^(3-)-(aq)+2H_(2)O(l)`
(c )`2[Fe(CN)_(6)]^(3-)(aq)+2OH^(-)(aq)+H_(2)O(aq)rarr2[Fe(CN)_(6)]^(4)+(aq)+O_(2)+2 H_(2)O(l)`
(d) `BrO_(3)^(-)(aq) +F_(2)(g)+2 OH^(-)+2 OH^(-)(aq) rarr BrO_(4)^(-)(aq)+H_(2)O(l)`
(e )`2NaCI_(3)(Aq)+L_(2)(aq)rarr2NaIO_(3)rarr 2NaIO_(3)(aq)+CI_(2)(aq)`

Explanation

(a)`H^(+) (b)H_(2)O_(2) (c )[Fe(CN)]_(6)^(3-)(d)F_(2) (e )NaCIO_(3)`
Reductants : (a) `Zn(b)[Fe(CN)]_(6)^(4-) (c )H_(2)O_(2)(d) BrO_(3)^(-) (e )I_(2)`
