'''Hydronium''' is a common [[Polyatomic Ion]].  Its [[chemical formula]] is <math>H_3O^+</math>.

Hydronium is present in all aqueous solutions, as the acidic counterpart to the alkaline [[hydroxide]] (<math>OH^-</math>).  A hydronium ion will combine with a hydroxide ion to create two water (<math>H_2O</math>) molecules.  An imbalance will shift the [[pH]] down if hydronium is more dominant.
