In basic balancing, when an H+ and an OH- appear on the same side of the equation, what is formed?

Explanation:
When a proton (H+) meets a hydroxide (OH−), a proton transfer occurs and they neutralize to form water. In aqueous solution, H+ is effectively present as H3O+ (hydronium), but the direct combination with OH− yields H2O. So the net result of their interaction on the same side is water formation. This is why water is formed, not hydronium remaining or any other species like O2, and it aligns with the acid–base neutralization picture where protons combine with hydroxide to make H2O.
