The smaller the value of pKb :
Correct answer: B. The stronger the base
- A. The weaker the base
- B. The stronger the base
- C. The stronger the acid
- D. None of the above
Explanation
pKb is the negative logarithm of the base dissociation constant, K(-log Kb ). A smaller pKb value corresponds to a larger Kb value, which indicates a greater extent of dissociation and therefore a stronger base.

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.
