Copper(II) lactate, also referred to as cupric lactate, is the chemical compound with the formula Cu(C₃H₅O₃)₂. It is a green powder that readily dissolves in hot water to form a green solution, often more blue than the acetate. This complex has been used to modify the solubility of copper(II) in alkaline media, which allows controlled electrodeposition of cuprous oxide.^[2]
