Consider the reactions : Why does the same reductant, thiosulphate react differently with iodine and bromine?

Solution:

The normal oxidation no. of in is .

The normal oxidation no. of in is .

The oxidation no. of in is .

The oxidation no. of in is .

As is a more grounded oxidizing specialist than , it oxidizes of to a higher oxidation no. of in

As is a more vulnerable oxidizing specialist so it oxidizes of particle to a lower oxidation no. that is particles.

Hence, thiosulphate respond distinctively with and .
