Chapter 4, Problem 38CTQ

Interpretation Introduction

Interpretation: Whether conjugate acid with high $\text{p}{K}_a$ or low $\text{p}{K}_a$ will donate ${\text{H}}^{+}$ more easily should be determined.

Concept introduction: According to Bronsted-Lowry concept, substance that donates proton is termed as acid while that accepts or gains protons is called base. Species formed after loss of protons from acids are known as their respective conjugate bases whereas conjugate acid is produced by addition of protons to base. Strength of acid is determined by its $\text{p}{K}_a$ value while that of base is governed by its $\text{p}{K}_b$ value.
