This is its largest market. It is used as a fungicide (notably in "Bordeaux mixture" to protect vineyards) and an herbicide to control invasive aquatic plants and algae in ponds and reservoirs.
), which features vibrant, bright blue crystals. When dehydrated (anhydrous), it turns into a pale green or white powder. Production and Chemical Properties cupric sulfate
Because of its beautiful crystal structure, it is a staple in classrooms for teaching crystallization and displacement reactions. It is also a component in Benedict’s solution and Fehling’s solution , used to test for reducing sugars (like glucose). This is its largest market
Cupric sulfate is primarily produced by treating copper metal with hot concentrated sulfuric acid or by treating copper oxides with dilute sulfuric acid. When dehydrated (anhydrous), it turns into a pale
It serves as a mordant in textile dyeing , an electrolyte in copper electroplating, and a preservative for wood to prevent rot.
Chemically, it is highly soluble in water and acts as an electrolyte. One of its most famous laboratory uses is as a test for water: when water is added to white anhydrous copper sulfate, it turns blue, indicating a chemical rehydration. Key Applications
