Use the half-reaction method to balance each redox reaction occurring in acidic aqueous solution.
(a) \(\mathrm{ClO}_{4}^{~-}(a q)+\mathrm{Cl}^{-}(a q) \longrightarrow \mathrm{ClO}_{3}^{~-}(a q)+\mathrm{Cl}_{2}(g)\)
(b) \(\mathrm{MnO}_{4}^{~-}(a q)+\mathrm{Al}(s) \longrightarrow \mathrm{Mn}^{2+}(a q)+\mathrm{Al}^{3+}(a q) \)
(c) \(\mathrm{Br}_{2}(a q)+\mathrm{Sn}(s) \longrightarrow \mathrm{Sn}^{2+}(a q)+\mathrm{Br}^{-}(a q)\)

ANSWER:
Solution 67P: Here, We, are going to balance the equation.
Srep 1:
(a) ClO4− (aq) + Cl− (aq) → ClO3− (aq) + Cl2(g)
The balanced chemical equation is
ClO4− (aq) + 2Cl− (aq)+2 H+(aq) → ClO3− (aq) + Cl2(g)+ H2O(l)
