Which oxide of sulphur can act as both oxidizing and reducing agent ?

1.	Which oxide of sulphur can act as both oxidizing and reducing agent ? Give one example each.
Answer» Sulphur dioxide `(SO_(2))` acts as both oxidising as well as reducing agent. `SO_(2)` as Oxidising agent : Sodium sulphide oxidises to hypo with `SO_(2)`. `2Na_(2)S+3SO_(2)to2Na_(2)S_(2)O_(3)+S` `SO_(2)` as Reducing agent : `SO_(2)` reduces `Fe^(+3)` ions to `Fe^(+2)` ions. `2Fe^(+3)+SO_(2)+2H_(2)O to2Fe^(+2)+SO_(4)^(-2)+4H^(+)`

The heavier elements of groups 13 and 14 besides the group oxidation state exhibit another oxidation state which is two units lower than the group oxidation state and the stability of this lower oxidation state increases down the group. This concept which is commonly called inert pair effect has been used to explain many physical and chemical properties of the element of these groups. Element of group 13A. exhibit oxidation state of `+3` onlyB. form `M^(+)` and `M^(3+)` ionsC. exhibit oxidation states of +1 and +3D. form `M^(-)` and `M^(+)` ions
