hi all, my chemistry assignment had a bunch of questions on redox equations balancing. i got stuck on this one:

[tex] \CrI_{3} + KOH + \Cl_{2} \rightarrow \K_{2}CrO_{4} + \KIO_{4} + KCl + \H_{2}O [\tex]

so far, i tried to find ON numbers of the various elements.

Cr changes from +3 to +6

I changes from -1 to +7

Cl changes from 0 to +1

this means that Cr and I undergo a loss of electrons, while Cl undergoes a gain. i don't know how to solve this question when there are multiple LEO.

can you help? =)

[ EDIT : my attempt at LATEX has proved to be yet another disaster ]
