Used as a fungicide in agriculture to control fungal diseases on crops such as grapes, potatoes, and fruit trees. Commonly applied in vineyards as part of Bordeaux mixture to prevent mildew and other fungal infections. Employed in industrial settings for electroplating processes, where it serves as a source of copper ions to coat conductive surfaces with a thin, uniform layer of copper for improved conductivity and corrosion resistance. Utilized in mining and metallurgy for the flotation process of copper ores, aiding in the separation of valuable minerals from waste rock. Applied in water treatment to control algae growth in reservoirs, ponds, and swimming pools due to its algicidal properties. Used in animal husbandry as a dietary supplement in trace amounts to prevent copper deficiency in livestock, and sometimes in foot baths for cattle to treat hoof infections. Common in educational and laboratory settings for crystal growth experiments, electrochemistry demonstrations, and as a reagent in qualitative inorganic analysis.
