What is the reason for the formation of tribromo phenol when phenol is treated with aqueous bromine?

Explanation

To understand the formation of tribromophenol when phenol is treated with aqueous bromine, let's break down the process step by step.

### Step 1: Understanding Phenol in Aqueous Solution
When phenol (C6H5OH) is dissolved in water, it partially ionizes to form phenoxide ions (C6H5O⁻). This ionization occurs because phenol is a weak acid and can donate a proton (H⁺) to water.

**Hint:** Remember that phenol can act as an acid and form a phenoxide ion in aqueous solutions.
