Zinc carbonate is the inorganic compound with the formula ZnCO 3. It is a white solid that is insoluble in water. It exists in nature as the mineral smithsonite. It is prepared by treating cold solutions of zinc sulfate with potassium bicarbonate. Upon warming, it converts to basic zinc carbonate (Zn 5 (CO 3) 2 (OH) 6). [6]
Compounds with zinc in the oxidation state +1 are extremely rare. [5] The compounds have the formula RZn 2 R and they contain a Zn — Zn bond analogous to the metal-metal bond in mercury(I) ion, Hg 2 2+. In this respect zinc is similar to magnesium where low-valent compounds containing a Mg — Mg bond have been characterised. [6]
The bicarbonate ion (hydrogencarbonate ion) is an anion with the empirical formula HCO − 3 and a molecular mass of 61.01 daltons; it consists of one central carbon atom surrounded by three oxygen atoms in a trigonal planar arrangement, with a hydrogen atom attached to one of the oxygens.

Carbonic anhydrase was initially isolated and characterised from red blood cells in 1933, with simultaneous reports by Meldrum and Roughton (at Cambridge University in the United Kingdom) and by Stadie and O’Brien (at the University of Pennsylvania in the United States), [7] [8] both while searching for a "catalytic factor... necessary for rapid transit of the HCO 3-[bicarbonate anion] from ...
