Question

The equivalent of iodine in the reaction 2na2s2o3 + i2 gives lies to 2nai + na2s4o6 is

Answer 1

Answer:

Oxidation state of I changes from 0 to −1.

Therefore, change in oxidation state is 1.

Change, per mole of iodine molecule is 1×2 (as we have two atoms of I) = 2.

So, Eq. Wt is =

2
