AHydroxide ions, OH-
BHydronium ions, H3O+
COxide ions, O2-
DPeroxide ions, O2 2-
Answer & Solution
Correct answer: B. Hydronium ions, H3O+
1. An acid dissolves in water and yields hydronium ions.
2. HCl plus water gives Cl- and H3O+, which confirms that hydrogen chloride is an acid.
3. A base is the species that yields hydroxide ions instead.
4. Oxide and peroxide ions play no part in this definition.
