Does copper carbonate dissolve in water?

Yes, but only in a very limited range of solutions. The most soluble form of copper carbonate is Cu2(OH)3Cl, also called dicopper chloride trihydroxide, which is a greenish crystalline solid encountered in mineral deposits, metal corrosion products, industrial products, art and archeological objects, and some living systems.

It is prepared by the reaction of a hot solution of CuCl2 with freshly precipitated CuO (eq. 4), or by hydrolysis of CuSO4 with alkali in the presence of sufficient chloride ions (eq. 5).

Soluble compounds of group 1 and 2 include ionic carbonates, which contain the carbonate ion CO32-, and hydrogen carbonates, which contain the bicarbonate ion HCO3. Examples of these are calcium carbonate (CaCO3), iron(II) carbonate (FeCO3), magnesium carbonate (MgCO3), and siderite.

Gluconate forms a strong bond with copper and is the main source of the copper ion in infant formula milk, drinks, salts, and health foods. It is used to help promote bone, haemoglobin and red blood cell formation and aid in the production of collagen.

The ionic form of copper is the most soluble and available for use by animals and humans, but inorganic copper is also required for many important functions. Solgar Chelated Copper provides this element as a chelated form, which allows the body to utilise it in a more effective manner.

It is also essential for the production of protein, energy, hair and skin colouring, and taste sensitivity. Copper deficiency can lead to a number of health problems including osteoporosis, anemia, and general weakness.
