Answered: Pls solve this question correctly in 5 | bartleby Expert Answer. Acids and bases exist as conjugate acid-base pairs.The term conjugate comes from the Latin stems meaning "joined together" and refers to things that are joined, particularly in pairs, such as Brnsted acids and bases.. Every time a Brnsted acid acts as an H +-ion donor, it forms a conjugate base.Imagine a generic acid, HA. Thus the product of the acid constant for a weak acid and the base constant for the conjugate base must be Kw, and the sum of p Ka and p Kb for a conjugate acid-base pair is 14. Contact. solvent.
