Question

I2 + NaOH ------ NaIO3 + NaI + H2O
BALANCE THE EQUATION BY OXIDATION NUMBER METHOD AND EXPLAIN EACH STEP

Answer 1

I₂ + NaOH = NaIO₃ + NaI + H₂O

In the oxidation number method, you determine the oxidation numbers of all atoms. Then you multiply the atoms that have changed by small whole numbers.

You are making the total loss of electrons equal to the total gain of electrons. Then you balance the rest of the atoms.

So after balancing we get,

3I₂ + 6NaOH = NaIO₃ + 5NaI + 3H₂O

Answer 2

I2+NaOH=Nalo3 +Nal+H2O
