Commonly used in electroplating baths to deposit copper coatings on metals, providing a smooth and conductive surface for further plating or finishing. Employed in water treatment to control algae growth in reservoirs, ponds, and swimming pools due to its algaecidal properties. Utilized in the preparation of catalysts and in organic synthesis as a drying agent or reagent in various chemical reactions. Found in educational and research laboratories for crystal growth experiments and as a source of copper ions in biochemical assays. Used in the textile industry for dyeing processes, where it acts as a mordant to fix dyes on fabrics. Applied in the leather tanning industry to improve the resistance of leather to microbial attack and to enhance color.
