Consider the redox reaction
`2S_(2)O_(3)^(2-)+I_(2)rarrS_(4)O_(6)^(2-)+2I^(ө)`
A. `S_(2)O_(3)^(2-)` gets reduced to `S_(4)O_(6)^(2-)`
B. `S_(2)O_(3)^(2-)` gets oxidised to `S_(4)O_(6)^(2-)`
C. `I_(2)` gets reduced to `I^(ө)`
D. `I_(2)` gets oxidised to `I^(ө)`
`2S_(2)O_(3)^(2-)+I_(2)rarrS_(4)O_(6)^(2-)+2I^(ө)`
A. `S_(2)O_(3)^(2-)` gets reduced to `S_(4)O_(6)^(2-)`
B. `S_(2)O_(3)^(2-)` gets oxidised to `S_(4)O_(6)^(2-)`
C. `I_(2)` gets reduced to `I^(ө)`
D. `I_(2)` gets oxidised to `I^(ө)`
Correct Answer – B::C
`2S_(2)O_(3)^(2-)rarrS_(4)O_(6)^(2-)+2e^(-) (“Oxidation”)`
`I_(2)+2e^(-)rarr2I^(ө)(“Reduction”)`
