Used as a fungicide in agriculture to control fungal diseases on crops such as grapes, potatoes, and fruits. 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 surfaces with a thin layer of metal for conductivity or corrosion resistance. Utilized in mining and metallurgy for the extraction and purification of metals, particularly in solvent extraction and electrowinning operations. Applied in water treatment to control algae growth in reservoirs, ponds, and swimming pools due to its algaecidal properties. Used in animal husbandry as a dietary supplement in trace amounts to prevent copper deficiency in livestock, though careful dosing is required to avoid toxicity. Found in educational laboratories for chemistry experiments involving crystal growth, electrochemistry, and displacement reactions.
