Hello. I was wondering if anyone could help me balance this equation using the methods I said in the subject line. Thanks!

IO₃^-(aq) + I^-(aq) = I₃^-(aq)

This is an acidic reaction, I don't know if that is obvious or not.

If I didn't misread your post, you want to balance this quation using half-equation method, right?(Just for confirmation - not saying this method is wrong)

IO₃^-(aq) + I^-(aq) = I₃^-(aq)

Obviously, you have IO₃^-(aq) and I^-(aq) from the start, and these two chemicals will both be oxidized/reduced to I₃^-(aq). So, you need to balance the following two half equations:

IO₃^-(aq)  I₃^-(aq)

I^-(aq)  I₃^-(aq)

Try to proceed from here.
