First of all that H should be H+ to correctly balance the equation IIRC Lewis does not apply here because there are no lone pairs. For the acid/base part, you know what an acid does. It donates protons. So you'll have
C₆H₈O₆ → C₆H₆O₆ + H⁺
2H⁺ + 2I^- → 2 H⁺I^-
The acid base pair would be C₆H₈O₆ / C₆H₆O₆
For the report, I can't help with that.
I hope I remember this correctly, it's been a while since I've done this so I may be wrong.
