Which of the following compounds is the strongest Bronsted acid
Correct answer: A. HCl
- A. HCl
- B. H2S
- C. HBr
- D. H20
Explanation
HCl is a strong Bronsted acid because it readily donates a proton (H⁺ ion) when dissolved in water, forming the hydronium ion (H₃O⁺). This dissociation occurs almost completely in aqueous solution.

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.
