Chapter 20.7, Problem 18P

Interpretation Introduction

Interpretation:

The percent of imidazole protonated at physiological $\text{pH}\left(7.4\right)$ has to be given.

Concept Introduction:

The role of $pH$ value:

The value of $\text{pH}$ ranges from $1\text{to}14$, If the value of $\text{pH}$ is less than $7$ then solution will be acidic in nature, whereas the $\text{pH}$ value more than $7$ results in the formation of a basic solution. An acidic strength results in the more formation of the hydrogen ions and less $\text{pH}$ value of the solution. Protonation is the process of an addition of hydrogen ion to form a conjugate acid.
