Which of the following is called hydrated proton?
Correct answer: C. Hydronium ion
- A. Oxonium ion
- B. Hydroxonium ion
- C. Hydronium ion
- D. Hydroxyl ion
Explanation
The correct answer is Hydronium ion. When an acid dissolves in water, the hydrogen ion (H+) does not exist freely but associates with a water molecule to form the hydronium ion (H3O+), which is commonly referred to as a hydrated proton.The Oxonium ion is another name for the hydronium ion, but it is not as widely used as 'hydronium ion' for this specific context. The term Hydroxonium ion is incorrect and does not exist in proper chemical nomenclature. The Hydroxyl ion (OH-) is related to bases, not acids, and does not involve a hydrated proton.

About Acids, Bases and Salts
Acid and base behaviour is explained through the Bronsted-Lowry transfer of protons and the Lewis donation or acceptance of electron pairs. The topic includes pH, pOH, ionisation and water equilibrium, plus salt formation and hydrolysis, where a salt solution may become acidic, basic or neutral.
