ZnCl2 battery grade Zinc Chloride 25% factory price CAS:7646-85-7 in bulk

1. Chemical Composition: Zinc chloride (ZnCl₂) 25% solution consists of zinc ions (Zn²⁺) and chloride ions (Cl⁻) dissolved in water.

2. Concentration:

• The solution is standardized to contain 25% (w/v) zinc chloride. This means that for every 100 milliliters of solution, there are 25 grams of zinc chloride present.

3. Physical Properties:

• Appearance: Zinc chloride 25% solution typically appears as a clear or slightly yellowish liquid.
• Density: The density of the solution varies depending on factors such as temperature and concentration but is generally close to the density of water.

4. Chemical Properties:

• Solubility: Zinc chloride is highly soluble in water, forming a clear solution.
• Hygroscopic: It may absorb moisture from the surrounding environment.

5. Industrial Applications:

• Galvanizing: Zinc chloride solutions are commonly used in the galvanizing process to coat iron and steel surfaces with a layer of zinc for corrosion protection.
• Metal Etching: They are utilized in metal etching processes for various applications, including circuit board manufacturing and artistic endeavors.
• Flux: Zinc chloride solutions serve as fluxes in soldering, brazing, and welding applications to remove oxides and other impurities from metal surfaces.

6. Laboratory Uses:

• Chemical Synthesis: Zinc chloride solutions are used as catalysts or reagents in organic synthesis reactions, such as Friedel-Crafts acylation and Beckmann rearrangement.
• Desiccant: They are employed as desiccants due to their hygroscopic properties, absorbing moisture from the air.

7. Battery Manufacturing:

• Electrolyte: Zinc chloride solutions are utilized as electrolytes in certain types of batteries, such as zinc-carbon batteries, due to their conductivity and chemical stability.

8. Safety Considerations:

• Corrosivity: Zinc chloride solutions can be corrosive to metals and tissues, requiring careful handling and storage.
• Toxicity: While zinc chloride is less toxic compared to other zinc compounds, ingestion or inhalation of large quantities can still lead to health issues. Proper safety precautions, such as wearing gloves and goggles, should be followed when handling the solution.

9. Environmental Impact:

• Disposal: Proper disposal of zinc chloride solutions is necessary to prevent environmental contamination. Neutralization and treatment methods should be employed to minimize the release of zinc into the environment.
• Ecosystem Impact: Zinc chloride can have adverse effects on aquatic life if released into water bodies, necessitating caution in its handling and disposal near sensitive ecosystems.

10. Storage and Handling:

• Stability: Zinc chloride solutions should be stored in tightly sealed containers away from heat and moisture to prevent decomposition.
• Compatibility: Care should be taken to avoid contact with incompatible materials, such as strong bases or reducing agents, which may react with zinc chloride and generate hazardous byproducts.
