Zinc chloride (ZnCl₂) is an inorganic compound made up of zinc and chlorine. It is typically encountered as a white, odorless, highly soluble solid that can appear as either a crystalline or granular material. It has a variety of uses across different industries due to its unique chemical properties.

Key Properties of Zinc Chloride:

• Chemical Formula: ZnCl₂
• Molar Mass: 136.3 g/mol
• Appearance: White crystalline solid or granular
• Solubility: Highly soluble in water, alcohol, and ether.
• Melting Point: 275°C (527°F)
• Boiling Point: 732°C (1,350°F)

Common Applications of Zinc Chloride:

1. Industrial Uses:
   • Flux in Metalworking: Zinc chloride is used as a flux in soldering and galvanizing processes to prevent the oxidation of metals.
   • Wood Preservation: It’s used as a wood preservative to protect wood from decay and pests.
   • Textile Industry: It is used in the manufacture of rayon, a type of synthetic fiber.
   • Chemical Synthesis: Zinc chloride is used as a catalyst or a reagent in various chemical reactions, especially in organic synthesis.
2. Electronics and Batteries:
   • Used in the production of dry-cell batteries (such as zinc-carbon batteries).
3. Antiseptic and Disinfectant:
   • In diluted forms, it can be used as a disinfectant or antiseptic in medical treatments for minor wounds and skin infections.
4. Water Treatment: Zinc chloride is used in some water treatment processes, such as coagulation or flocculation.

Safety Considerations:

• Toxicity: It can be toxic if ingested or inhaled in large amounts. It can irritate the skin, eyes, and respiratory system.
• Corrosive: It is a corrosive material, and caution should be taken when handling it, particularly in its concentrated form.
• Environmental Impact: It can be harmful to aquatic life if released into water bodies, and it is generally advised to handle and dispose of it carefully.

Reactions:

• Hydrolysis: When it dissolves in water, it can hydrolyze to form acidic solutions.

• Reaction with Bases: Zinc chloride can react with strong bases to form zinc hydroxide.

Given its versatility, zinc chloride is widely used in both industrial and scientific applications, though careful handling is necessary to avoid harm to health and the environment.
