Explanation / Answer

I- + IO4^- ............> I3^- + IO3^-

First half reaction

I- .........> I3^-

balance the I atoms

3I^- .............> I3^-

balance the charge

3I^- ............> I3^- + 2e- ................1

second half reaction

IO4^- ............> IO3^-

balance the O atoms with OH- ion on the left side

IO4^- ............> IO3^- + OH-

balance H atoms with H2O molecule on the left side and one OH- on the right side

IO4^- + H2O ............> IO3^- + 2OH-

balance the charge with e- adding

IO4^- + H2O + 2e- ............> IO3^- + 2OH-   .........................2

do eq.1 + eq.2

IO4^- + H2O + 3I- ............> IO3^- + 2OH- + I3^-
