State the reaction taking place when : Bromine water is added to the aqueous solution of aniline.

Explanation

### Step-by-Step Text Solution:

1. **Identify the Reactants**: The reactants in this reaction are aniline (C6H5NH2) and bromine water (Br2 in H2O).

2. **Understanding the Reaction**: When bromine water is added to aniline, a bromination reaction occurs. Aniline is a basic aromatic amine, and it can react with bromine to form a bromo-substituted product.

3. **Decolorization of Bromine Water**: The addition of aniline to bromine water leads to the decolorization of the bromine water. This indicates that bromine is being consumed in the reaction.
