alleryAll acids in aqueous solution release:
AHydroxide ions (OH⁻)
BHydronium ions (H₃O⁺)
CSodium ions (Na⁺)
DChloride ions (Cl⁻)
Answer & Solution
Correct answer: B. Hydronium ions (H₃O⁺)
1. Acid in water: HA + H₂O → A⁻ + H₃O⁺.
2. The hydronium ion H₃O⁺ is responsible for the sour taste and characteristic acid behaviour.
3. Bases release OH⁻ instead.
