Chapter 13, Problem 158AE

(a)

Interpretation Introduction

Interpretation: The $\text{0}\text{.10}$ solution of given compounds are to be rank in order of increasing $\text{pH}$ values.

Concept introduction: The scale of acidity from $\text{0}$ to $\text{14}$ is known as $\text{pH}$ scale. The value of $\text{pH}$ less than seven is considered as acid whereas the value of $\text{pH}$ greater than seven is considered as base.

The $\text{pH}$ value of strong acid is very less (close to $\text{1}$) whereas the $\text{pH}$ value of strong base is high (close to $\text{14}$).

To arrange: The compound $\text{HI,}\text{HF,}\text{NaF,}\text{NaI}$ in order of increasing $\text{pH}$ values.
