Copper;sulfate;pentahydrate

Copper sulfate pentahydrate is an inorganic compound with the chemical formula CuH10O9S and CAS number 7758-99-8. This crystalline salt contains five molecules of water per copper sulfate unit, giving it its pentahydrate designation. With a molecular weight of 249.69 g/mol, it appears as bright blue crystals and is highly soluble in water. It is classified as a hazardous substance with acute toxicity, eye damage potential, and aquatic toxicity properties.

Copper sulfate pentahydrate is a bright blue crystalline solid that is highly soluble in water, forming blue solutions. It is odorless and has a molecular weight of 249.69 g/mol. The compound is hygroscopic, meaning it can absorb moisture from air. When heated, it loses its water of crystallization, turning white and becoming anhydrous copper sulfate. It exhibits good thermal stability under normal conditions but decomposes at high temperatures.

Copper sulfate pentahydrate is widely used in agriculture as a fungicide and herbicide, particularly in vineyard treatments. It serves as a key component in industrial processes including electroplating, metal finishing, and as a catalyst in chemical reactions. The compound is also utilized in water treatment facilities for algae control, in textile dyeing processes, and in the production of other copper compounds. Additionally, it finds applications in laboratory analysis and educational demonstrations.

Copper sulfate pentahydrate requires careful handling due to its Acute Tox. 4 and Eye Dam. 1 classifications. Essential personal protective equipment includes chemical-resistant gloves, safety goggles or face shield, and protective clothing to prevent skin contact. Work in well-ventilated areas to avoid inhalation of dust particles. Avoid generating dust during handling and use appropriate dust control measures. Never eat, drink, or smoke while handling the substance, and wash hands thoroughly after use.

Copper sulfate pentahydrate should be stored in a cool, dry, well-ventilated area away from incompatible materials such as strong acids and alkalis. Keep containers tightly closed to prevent moisture absorption and contamination. Store away from heat sources and direct sunlight in original labeled containers. Ensure storage areas have appropriate spill containment measures and restrict access to authorized personnel only. Separate from food, feed, and drinking water to prevent accidental contamination.

Immediate action is required upon contact with copper sulfate pentahydrate due to its corrosive properties. For eye contact, flush immediately with plenty of water for at least 15 minutes and seek medical attention urgently. If skin contact occurs, wash thoroughly with soap and water. In case of ingestion, rinse mouth and drink water, but do not induce vomiting. For inhalation exposure, move to fresh air immediately. Always seek medical attention for any significant exposure.

Copper sulfate pentahydrate disposal must comply with local and national hazardous waste regulations due to its environmental toxicity classification (Aquatic Acute 1, Aquatic Chronic 1). The substance cannot be disposed of in regular waste streams or sewers. Contact licensed hazardous waste disposal companies for proper treatment and disposal. Small laboratory quantities may be neutralized and treated according to institutional waste management protocols. Always consult local environmental authorities for specific disposal requirements in your region.

Copper sulfate pentahydrate is classified under ADR transport regulations as Class 6.1 (toxic substances), Packing Group III. This classification requires specific packaging, labeling, and documentation for road transport. Packages must display appropriate hazard labels and UN identification numbers. Transport vehicles require proper placarding and emergency equipment. Only authorized carriers with appropriate training and certification should handle the transportation. Ensure compliance with international transport regulations for cross-border shipments.

Copper sulfate pentahydrate is subject to comprehensive European chemical regulations including REACH registration requirements and CLP classification obligations. The substance displays mandatory hazard pictogrammes GHS07, GHS05, and GHS09, with the signal word 'Danger'. While not currently listed as a SVHC (Substance of Very High Concern), its aquatic toxicity properties may subject it to additional environmental restrictions. Industrial users must comply with occupational exposure limits and environmental discharge regulations in their respective countries.
