Appearance of Basic Copper Chloride: grass green monoclinic crystalline fibrous mass or dark green powder
Characteristics of basic copper chloride: insoluble in water, soluble in acid; Easy to decompose when heated; Can react with hydrochloric acid, sodium carbonate solution is added into copper salt to obtain basic copper carbonate precipitate; Basic Copper Carbonate can be used as pigment, insecticide and sterilant, flare, etc.
Solubility of basic copper carbonate: insoluble in cold water and alcohol, soluble in acid, cyanide, ammonia water and ammonium salt.
Physical properties of basic copper carbonate: the precipitate obtained from the solution shows green color at the beginning and turns dark green color in the solution after standing. It is insoluble in water and soluble in acid. It is also soluble in cyanide, ammonium salt and alkali metal carbonate aqueous solution to form copper complex. Cu2(OH)2CO3: Dark sky blue very bright monoclinic crystal, or compact crystal cluster. It is insoluble in water, soluble in ammonia water and hot and concentrated sodium bicarbonate solution to form blue.
