Question

Which of the following are conjugate acid-base pairs and why ?


a) NaF and F -
b) HNO3 and HNO2
c) HI and I -
d) CH3COOH and CH3COO -
e) NH3 and NH2-

Answer 1

You need to learn how to recognize conjugate acid-base pairs so that you don't have to keep asking similar questions.

In a conjugate acid-base pair, the difference between the two substances is that one of them (the acid) will have an extra proton (H+) that the base doesn't have.

So c, d and e all show conjugate acid base pairs

Answer 2

option (c), (d) and (e) are examples of conjugate acid base pairs.
