It is an ionic compound ( a salt ) consisting of the ions copper ( II ) Cu 2 + , carbonate CO 2 − 3 , and hydroxide HO − . The name most commonly refers to the compound with formula Cu 2CO 3 ( OH ) . It is a green crystalline solid that occurs in nature as the mineral malachite . It has been used since antiquity as a pigment , and it is still used as such in artist paints , sometimes called verditer , green bice , or mountain green . Sometimes the name is used for Cu 3 ( CO 3 ) ( OH ) , a blue crystalline solid also known as the mineral azurite . It too has been used as pigment , sometimes under the name mountain blue or blue verditer . Both malachite and azurite can be found in the verdigris patina that is found on weathered brass , bronze , and copper . The composition of the patina can vary , in a maritime environment depending on the environment a basic chloride may be present , in an urban environment basic sulfates may be present . This compound is often improperly called ( even in chemistry articles ) copper carbonate , cupric carbonate , and similar names . The true ( neutral ) copper ( II ) carbonate CuCO is not known to occur naturally . It is decomposed by water or moisture from the air , and was synthesized only in 1973 by high temperature and very high pressures . Contents ( hide ) 1 Preparation 2 Reactions 3 Uses 4 References 5 External links Preparation ( edit ) Basic copper ( II ) carbonate patina on roofs of Château Frontenac . Basic copper carbonate is prepared by combining aqueous solutions of copper ( II ) sulfate and sodium carbonate at ambient temperature and pressure . Basic copper carbonate precipitates from the solution , with release of carbon dioxide CO 2 : 2 CuSO + 2 Na CO + H O → Cu ( OH ) CO + 2 Na SO + CO Basic copper carbonate can also be prepared by reacting aqueous solutions of copper ( II ) sulfate and sodium bicarbonate at ambient conditions . Basic copper carbonate precipitates from the solution , again with release of carbon dioxide : 2 CuSO + 4 NaHCO → Cu ( OH ) CO + 2 Na SO + 3 CO + H O Reactions ( edit ) Basic copper carbonate is decomposed by acids , such as solutions of hydrochloric acid HCl , into the copper ( II ) salt and carbon dioxide . `` Copper carbonate '' was the first compound to be broken down into several compounds : in 1794 by the French chemist Joseph Louis Proust ( 1754 -- 1826 ) thermally decomposed it to CO and CuO , cupric oxide , a black solid . The basic copper carbonates , malachite and azurite , both decompose forming CO and CuO , cupric oxide . Uses ( edit ) Deborah Kip , wife of Balthasar Gerbier , and her children ( Peter Paul Rubens , 1629 - 1630 ) Both malachite and azurite basic copper carbonates have been used as pigments . One example of the use of both azurite and its artificial form blue verditer is the portrait of the family of Balthasar Gerbier by Peter Paul Rubens . The green skirt of Deborah Kip is painted in azurite , smalt , blue verditer ( artificial form of azurite ) , yellow ochre , lead - tin - yellow and yellow lake . The green color is obviously achieved by mixing blue and yellow pigments . It has also been used in some types of make - up , like lipstick , although it can also be toxic to humans . It also has been used for many years as an effective algaecide in farm ponds and in aquaculture operations .
