Question

The oxidation states of sulphur in the anions `SO_(3)^(2-), S_(2)O_(4)^(2-)`, and `S_(2)O_(6)^(2-)` follow the order
A. `S_(2)O_(6)^(2-) lt S_(2)O_(4)^(2) lt SO_(3)^(2-)`
B. `S_(2)O_(4)^(2-) lt SO_(3)^(2-) lt S_(2)O_(6)^(2-)`
C. `SO_(3)^(2-) lt S_(2)O_(4)^(2-) lt S_(2)O_(6)^(2-)`
D. `S_(2)O_(4)^(2) lt S_(2)O_(6)^(2-) lt SO_(3)^(2-)`

Answer 1

Correct Answer - B
`S_(2)O_(4)^(2-) lt SO_(2)^(2-) lt S_(2)O_(6)^(2-)`
Oxidation state of sulphur in `S_(2)O_(4)^(2-)=+3`
Oxidation state of sulphur in `SO_(3)^(2-) =+4`
Oxidation state of sulphur in `S_(2)O_(6)^(2-) = +5`.
