In acid base reaction, how many conjugate pairs are formed?
Correct answer: B. Two
- A. One
- B. Two
- C. Three
- D. Four
Explanation
In a standard acid-base reaction, two conjugate pairs are formed. The acid donates a proton to become a conjugate base, while the base accepts a proton to become a conjugate acid. Therefore, Option B is correct. Option A is incorrect as it underestimates the number of conjugate pairs. Options C and D are incorrect because they overestimate the number of conjugate pairs formed in a typical acid-base reaction.

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.
