Na_(2)S_(2)O_(3) may react with the compound given in Column-I, Na_(2)

1.	Na_(2)S_(2)O_(3) may react with the compound given in Column-I, Na_(2)S_(2)O_(3)exhibits the properties of the type give in the coloumn-II, matter the reactantsgiven in column-Iwith the type of property, propertiesgiven in Column-II {:("COLUMN-I","COLUMN-II"),("(Reactant)","(Type of property)"),((A)Cl_(2),(p)"Complexing agent"),((B)AgBr,(q)"Disproportionation"),((C )HCl,(r )"Only as reductant"),((D)I_(2),(s) "An antichlor"):}
Answer» Solution :A) `Na_(2)S_(2)O_(3)+Cl_(2)+H_(2)O to Na_(2)SO_(4)+2HCL+S-` Hence it act as antichlor and it is oxidized by `Cl_(2)`. B) `2Na_(2)S_(2)O_(3)+AgBr to Na_(3)[Ag(S_(2)O_(3))_(2)]+NaBr-` Used photography fixing AGENT i.e., COMPLEXING agent. C) `Na_(2)S_(2)O_(3)+2HCl to 2NaCl+SO_(2)+S+H_(2)O-` Disproportional reaction. D) `2Na_(2)S_(2)O_(3)+I_(2) to Na_(2)S_(4)O_(6)+2NaI-` It is oxidized by `I_(2)` quantitatively.
