Thiosulphate reacts differently with iodine and bromine in the reaction given below : 2 {\S}_2 {\O}_3^{2-}+ {\I}_2 \rightarrow {\S}_4 {\O}_6^{2-}+2 {\I}^{-} {\S}_2 {\O}_3^{2-}+5 {\Br}_2+5 {\H}_2 {\O} \rightarrow 2 {\SO}_4^{2-}+4 {\Br}^{-}+10 {\H}^{+} Which of the following statement justifies the above dual behaviour of thiosulphate? [8 Apr 2024 Shift 1]

Correct Answer is : Bromine is a stronger oxidant than iodine

Bromine undergoes oxidation and iodine undergoes reduction by iodine in these reactions

Thiosulphate undergoes oxidation by bromine and reduction by iodine in these reaction

Bromine is a stronger oxidant than iodine

Bromine is a weaker oxidant than iodine
