Conjugate base of a weak acid:
Correct answer: B. Strong
- A. Weak
- B. Strong
- C. Unstable
- D. None of these options
Explanation
Weak acids have strong bonds to their H+. Strong acids have weak bonds to their H+. Weak bases have a strong tendency to get H+ and/or donate an electron pair. Strong bases have a weak tendency to get H+ and/or donate an electron pair. Hence conjugate base of weak acid is strong. So, B is the correct option.

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.
