To understand what happens when sodium chloride (NaCl) is added to a colloidal solution of ferric hydroxide (Fe(OH)₃), we can break down the process into several steps:
### Step 1: Understanding the Components
- Ferric hydroxide is a colloidal solution consisting of Fe³⁺ ions and OH⁻ ions. In this colloidal state, the particles are stabilized and dispersed in the solution.
- Sodium chloride (NaCl) dissociates in solution into sodium ions (Na⁺) and chloride ions (Cl⁻).
### Step 2: Dissociation of Sodium Chloride
- When NaCl is added to the ferric hydroxide solution, it dissociates into Na⁺ and Cl⁻ ions. This can be represented as:
