Question

Thiosulphate reacts differently with iodine and
bromine in the reactions given below:
2S₂O²⁻₃+I₂ ⟶ S₄O²⁻₆+ 2I⁻
S₂O²⁻₃+ Br₂+ 5H₂O⟶ 2SO²⁻₄+ 2Br⁻+ 10H⁻
Which of the following statements justifies the
above dual behaviour of thiosulphate?
(a) Bromine is a stronger oxidant than iodine.
(b) Bromine is a weaker oxidant than iodine.
(c) Thiosulphate undergoes oxidation by
bromine and reduction by iodine in these reactions.
(d) Bromine undergoes oxidation and iodine
undergoes reduction in these reactions.
