Question

Balance the following equation by ion electron method: Na₂S₂O3+I₂-Na₂S.O6 +Nal​

Answer 1

Answer:

Na2S2O3 +I2 = Na2S4O6+NaI balance the equation by ion electron method.

here we see iodine , I2 is reduced (as oxidation number changes from 0 to -1) and sulphur is oxidised. ( as oxidation number of s changes from +2 to +2.5)

now adding  ions both sides in equations (1) and (2)

then, ....(1)

and ....(2)

now adding equations (1) and (2) we get,

This is our balanced chemical equation.
