Thiosulphate reacts differently with iodine and bromine in the reactio

1.	Thiosulphate reacts differently with iodine and bromine in the reactions given below 2S_(2)O_(3)^(-2)+I_(2)toS_(4)O_(6)^(-2)+2I^(-) 2S_(2)O_(3)^(-2)+2Br_(2)+5H_(2)Oto2SO_(4)^(-2)+2Br^(-)+10H^(+) Which of the following statements justifies the above dual behaviour of thiosulphate ?
Answer» Bromine is stronger oxidants than iodine. Bromine is weaker OXIDANT than iodine. Thiosulphate undergoes oxidation by bromine and reduction by iodine in these reactions. Bromine undergoes oxidation and iodine undergoes reduction in these reactions. Solution :Because `I_(2)` is OXIDISING `S_(2)O_(3)^(-2)` into `S_(4)O_(6)^(-2)`. White `Br_(2)` is oxidising `S_(2)O_(3)^(-2)` into `SO_(4)^(-2)`.
