Question
Answer the following in brief :
What is meant by conjugate acid-base pair?
Solution
i. The base produced by releasing the proton from an acid is the conjugate base of that acid.
ii. Similarly, the acid produced when a base accepts a proton is called the conjugate acid of that base.
iii. A pair of an acid and a base differing by a proton is said to be a conjugate acid-base pair.
