Answer:
The oxidation reaction is
[tex]2 Cl ^{-} _{(aq)} + ---- > Cl_2_{(g)} + 2 e^{-}[/tex]
The reduction reaction is
[tex]BiO_3 ^-_{(aq)} + 3H_2O_{(l)} + 2e^{-} ---> Bi^{3+} + 6OH^{-}_{(aq)}[/tex]
Explanation:
From the question we are told that the redox reaction is
[tex]Cl_2__{(g) }}+ Bi^{3+} _{(aq)} + 6OH^-_{(aq)} = 2cl^-{(aq)} + BiO^{-3} _{(aq)} + 3H20 _{(l)}[/tex]
So the following are the concurrent oxidation a reduction reaction
Oxidation
[tex]2 Cl ^{-} _{(aq)} ---- > Cl_2_{(g)}[/tex]
Reduction
[tex]BiO_3^{-} _{(aq)} -----> Bi^{3+} _{(aq)}[/tex]
Oxidation
[tex]2 Cl ^{-} _{(aq)} ---- > Cl_2_{(g)}[/tex]
Reduction
[tex]BiO_3 ^- _{(aq)} + 3H_2 O_{l} ----> Bi^{3+} _{(aq)} + 6OH^{-}_{(aq)}[/tex]
Overall Oxidation
[tex]2 Cl ^{-} _{(aq)} + ---- > Cl_2_{(g)} + 2 e^{-}[/tex]
Overall Reduction
[tex]BiO_3 ^-_{(aq)} + 3H_2O_{(l)} + 2e^{-} ---> Bi^{3+} + 6OH^{-}_{(aq)}[/tex]
