What is the range of a pH indicator in terms of its dissociation constant `(K_(ln))`?

Explanation

To determine the range of a pH indicator in terms of its dissociation constant (K_indicator), we can follow these steps:

### Step 1: Understand the Relationship Between pK and K
The dissociation constant (K_indicator) of an indicator is related to its pK value by the formula:
\[ pK = -\log(K_{indicator}) \]

### Step 2: Define the pH Range of an Indicator
The pH range of a pH indicator can be defined as:
