Chapter 16, Problem 4A

Interpretation Introduction

Interpretation: Different components of a conjugate acid-base pair is to be studied.

Concept introduction: The concept of conjugate acid-base pair is given by Bronsted-Lowry.

According to it,

Acid is a substance which donate hydrogen ion and Base is a substance which accept hydrogen ion.

When acid donates $H^{+}$ , the species form is conjugate base and when base accepts $H^{+}$ , the species form is conjugate acid.

Answer to Problem 4A

The members of conjugate acid base pair differ from each or by just one proton hydrogen ion. For example $C{H}_{3}COOH$ and $C{H}_{3}CO{O}^{-}$ is an example of a conjugate acid-base pair. All bronzed acids have a conjugate base and all bronsted bases have a conjugate acid.

Explanation of Solution

The members of conjugate acid base pair differ from each or by just one proton hydrogen ion. For example $C{H}_{3}COOH$ and $C{H}_{3}CO{O}^{-}$ is an example of a conjugate acid-base pair. All bronzed acids have a conjugate base and all bronsted bases have a conjugate acid. 

Conclusion

Conjugate acid base pair differ from each or by just one proton hydrogen ion.
