Used in electroplating processes to deposit copper coatings on metals, providing corrosion resistance and improved conductivity. Commonly employed in the production of printed circuit boards. Acts as a catalyst in organic synthesis, particularly in oxidation and chlorination reactions. Utilized in textile printing and dyeing as a mordant to fix colors. Found in agricultural chemicals as a component of fungicides. Also used in wastewater treatment to control the growth of algae and bacteria. Used in educational laboratories for crystal growth experiments and electrochemistry demonstrations.
