Chapter 9, Problem 9.109E

Interpretation Introduction

Interpretation:

The explanation corresponding to the given statement that how the chemist could use a $\text{pH}$ meter or $\text{pH}$ paper to determine the flask that contains acid is to be stated.

Concept introduction:

The value of $\text{pH}$ ranges from $0$ to $14$. Higher is the concentration of hydronium ion; lower is the value of $\text{pH}$. A solution whose $\text{pH}$ value lies in between $0$ and $7$ is considered to be acidic while the solution whose $\text{pH}$ lies in between $7$ and $14$ is considered to be basic. The solution is said to be neutral if it has a $\text{pH}$ value equal to $7$.
