Cupric carbonate basic

Chemical properties

Copper carbonate (basic), dark green monoclinic crystals, insoluble in cold H20, decomposes in H20, soluble in potassium cyanide. Malachite, copper ore, is of this composition. Refmed compound is used as a pigment.

The Uses of Cupric carbonate basic

Used to kill algae and as a pigment

The Uses of Cupric carbonate basic

As seed treatment fungicide; in pyrotechnics; as paint and varnish pigment; in animal and poultry feeds; in sweetening of petrol sour crude stock; in manufacture of other Cu salts.

The Uses of Cupric carbonate basic

Copper(II) carbonate dihydroxide is used as pigments and in treatment for copper deficiency in ruminants. It is also used in pyrotechnics, in sweetening of petrol sour crude stock and animal and poultry feeds. It finds application in some types of make-up such as lipstick. In analytical chemistry, it is used as a reagent for analysis.

Preparation

Basic carbonate is obtained from its naturally occurring minerals. It also may be prepared by mixing a solution of copper sulfate with sodium carbonate. The precipitate is then filtered and dried.

General Description

Copper(II) carbonate basic is naturally found in azurite and malachite. On heating, it undergoes decomposition to form copper(II) oxide, carbon dioxide and water. Due to its high initial discharge capacity, copper(II) carbonate (basic) is being considered as a promising candidate as anode materials for lithium-ion batteries.

Hazard

Toxic by ingestion.
