Conjugate acid of a very strong base is relatively ...............
Correct answer: B. Very weak acid
- A. Strong acid
- B. Very weak acid
- C. Neutral
- D. Both a & b
Explanation
The strength of a base and its conjugate acid are inversely related. When a base is very strong, it easily accepts protons, meaning its conjugate acid does not easily donate protons, making it a very weak acid. Option B is correct because it aligns with this concept. A strong acid (Option A) is incorrect because a very strong base cannot form a strong conjugate acid. Neutral (Option C) is also incorrect since conjugate acids/bases are not inherently neutral. Option D is incorrect because it suggests a contradiction: a substance cannot be both a strong and weak acid simultaneously.

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.
