Chapter 17, Problem 17.39QP

Interpretation Introduction

Interpretation:

From the given acid dissociation constant and $\text{pH}$, the colour has to be identified.

Concept introduction:

• $\text{pH}$ is the logarithm of the reciprocal of the concentration  of ${\text{H}}_{\text{3}}{\text{O}}^{\text{+}}$ in a solution.
•   $\text{pH}$ is used to determine the acidity or basicity of an aqueous solution.

$\text{pH}$	Colour
Less than $3$	Red
$\text{3}\text{to}\text{6}$	Orange or yellow
$7$	green
$8\text{to}11$	Blue
Greater than $11$	Violet or indigo

To identify: the colour of the solution
