1. What are the main applications of ferric chloride solution?

• FeCl₃ solution is widely used as a coagulant in municipal and industrial water treatment, effectively removing turbidity, suspended solids, and color.
• FeCl₃ solution is applied in PCB etching for printed circuit board manufacturing.
• FeCl₃ solution serves as an oxidizing agent and raw material in chemical synthesis, metal processing, and corrosion control.

2. How does ferric chloride solution differ from ferrous chloride?

• FeCl₃ is in the +3 oxidation state, offering stronger coagulation and oxidizing ability than FeCl₂.
• Produces more stable flocs in water treatment applications.
• Has a longer shelf life and better stability under standard storage conditions.
• Ideal for applications requiring high oxidation potential, such as PCB etching and metal surface treatment.

3. How should ferric chloride solution be safely stored and handled?

• Storage: Keep in sealed, corrosion-resistant containers in a cool, dry, well-ventilated area. Avoid contact with metals that can corrode.
• Handling: Use PPE including gloves, goggles, and protective clothing. Avoid skin and eye contact.
• Shelf life: Stable for long-term storage if kept sealed and away from light and heat.
• Safety: Do not mix with incompatible chemicals such as strong bases. Handle according to chemical safety guidelines.
