Copper sulfate solution is widely used in agriculture as a fungicide and pesticide. It helps control fungal diseases in crops, particularly in vineyards, fruit trees, and vegetables. Mixed with lime, it forms Bordeaux mixture, a traditional spray for preventing mildew and other plant infections. In industrial settings, copper sulfate solution serves in electroplating processes, where it deposits a thin layer of copper onto metal surfaces for protection or decoration. It is also used in metal finishing and in the production of other copper-based chemicals. The solution finds use in water treatment to control algae growth in reservoirs, ponds, and swimming pools. It is effective even at low concentrations, making it a cost-efficient option for large-scale applications. In education and research laboratories, copper sulfate solution is commonly used in chemistry experiments, such as crystal growth, electrochemistry demonstrations, and displacement reactions. It is also employed in biology for testing the presence of proteins and in preparing growth media for certain microorganisms. Additionally, it plays a role in animal husbandry, where it is added in small amounts to livestock feed to prevent copper deficiency, though careful dosage is required to avoid toxicity.
