Question

what is the name of this ion? h₃o⁺ water positive hydrate trihydrogen oxide hydronium

Explanation:

• The ion \(H_3O^+\) is formed when a water molecule (\(H_2O\)) gains a hydrogen ion (\(H^+\)).
• In chemistry, this ion is specifically named the hydronium ion.
• "Water positive" is not a standard chemical name for this ion.
• "Hydrate" generally refers to a compound with water molecules associated with it (e.g., \(CuSO_4\cdot5H_2O\) is copper sulfate pentahydrate), not the \(H_3O^+\) ion.
• "Trihydrogen oxide" is an incorrect and non - standard name for \(H_3O^+\).

Answer:

hydronium
