Why is `Fe(OH)_(3)` colloid positively charged when prepared by adding `FeCl_(3)` to hot water ?

Explanation

To understand why `Fe(OH)_(3)` colloid is positively charged when prepared by adding `FeCl_(3)` to hot water, we can break down the process into several steps:

### Step-by-Step Solution:

1. **Dissolution of FeCl3**: When `FeCl3` is added to hot water, it dissolves and dissociates into its constituent ions:
\[ FeCl_3 \rightarrow Fe^{3+} + 3Cl^{-} \]
