Question
Hydronium Ions are always in the form $H _3 O$.
✓
Answer
Acids in water gives $H ^{+}$ions. These $H ^{+}$ions do not exist freely in water. This is because $H ^{+}$is a single proton, a hydrogen atom has only one proton and one electron. If the electron is removed to make $H ^{+}$, all that is left is an extremely tiny positively charged nucleus. This $H$ ion will immediately combine with the surrounding water $\left( H _2 O \right)$ molecules to form $\left( H _3 O _4\right)$ hydronium ion.
