A colloid is formed by adding `FeCl_(3)` in excess of hot water. What will happen if excess sodium chloride is added to this colloid?

Explanation

To solve the question regarding the effect of adding excess sodium chloride (NaCl) to a colloid formed by FeCl3 in hot water, we can break down the solution into the following steps:

### Step-by-Step Solution:

1. **Formation of the Colloid**:
- When FeCl3 is added to hot water, it dissociates into Fe³⁺ ions and Cl⁻ ions. In excess hot water, Fe³⁺ ions hydrolyze to form hydrated ferric oxide, which results in the formation of a positively charged colloidal solution (sol). This sol is primarily composed of hydrated ferric oxide (Fe(OH)3) particles suspended in water.

2. **Understanding the Colloid**:
