Widely used in agriculture as a fungicide and pesticide, especially in vineyards and orchards to control fungal diseases like mildew and blight. It is a key component of Bordeaux mixture, which protects plants when sprayed on leaves and stems. Also applied in seed treatment to prevent fungal infections during germination. In industry, used in electroplating processes to deposit copper on metal surfaces, improving conductivity and corrosion resistance. Employed in mining and metallurgy for the extraction and purification of metals through solvent extraction and electrowinning methods. Commonly used in water treatment to control algae growth in reservoirs, ponds, and swimming pools. Effective at low concentrations, though care is taken to avoid toxicity to aquatic life. In education and research, utilized in laboratory settings for crystallization experiments and as a reagent in qualitative inorganic analysis. Also used in school science projects due to its ability to form bright blue crystals. Applied in animal nutrition as a dietary supplement in trace amounts to prevent copper deficiency in livestock. However, it must be carefully dosed due to its toxicity at higher levels. Used in the preparation of other copper-based chemicals and in dyeing processes as a mordant to fix colors on textiles.
