kupariIIasetaatti

Kupari(II)asetaatti, also known as copper(II) acetate, is a chemical compound with the formula Cu(CH3COO)2. It typically exists as a hydrated salt, most commonly as the monohydrate, Cu(CH3COO)2·H2O. This salt is a crystalline solid, often appearing as green or blue-green crystals. It has a characteristic vinegar-like odor due to the presence of the acetate anion.

The solubility of copper(II) acetate varies with temperature. It is moderately soluble in water, and its solubility increases with heating. It is also soluble in ethanol. In aqueous solutions, it can undergo hydrolysis, leading to slightly acidic conditions. The anhydrous form is typically a white solid, but it readily absorbs moisture from the air to form the hydrated, colored species.

Copper(II) acetate has found various applications throughout history and in modern times. Historically, it was used as a pigment in paints and as a mordant in dyeing textiles. It has also been employed as a fungicide and insecticide in agriculture. In laboratory settings, it serves as a precursor for the synthesis of other copper compounds and as a catalyst in certain organic reactions, such as the Wacker process and the Ullmann reaction. It is also used in the production of Paris green, a historically significant but toxic pigment. Due to its toxicity, handling of copper(II) acetate requires appropriate safety precautions.
