Bromophenol blue is an indicator with a `K_(a)` value of `5.84 xx 10^(-5)`. What is the percentage of this indicator in its basic form at a `pH` of `4.84`?

Explanation

To find the percentage of bromophenol blue in its basic form at a pH of 4.84, we can follow these steps:

### Step 1: Understand the dissociation of bromophenol blue
Bromophenol blue acts as a weak acid and can be represented as:
\[ \text{HIn} \rightleftharpoons \text{H}^+ + \text{In}^- \]
Where:
- \(\text{HIn}\) is the acidic form.
- \(\text{In}^-\) is the basic form.
