Science / Chemistry / Carbonate: (CO32-) 1. An inorganic ion with a charge of -2, containing carbon bound directly to three oxygens in a in a flat triangular arrangement. 2. A compound containing CO32- ions.

Carbonate Rock

Science / Geology / Carbonate Rock: A rock made up primarily of carbonate minerals (minerals containing the CO3 anionic structure). Limestone (made up primarily of calicite - CaCO3) and dolostone (made up primarily of dolomite - CaMg (C MORE

Carbonate Hardness

Science / Chemistry / Carbonate Hardness: Water hardness due to the presence of calcium and magnesium carbonates and bicarbonates. The 'noncarbonate hardness' is due mostly to calcium and magnesium sulfates, chlorides, and nitrates. MORE

Carbonate Platform

Science / Geology / Carbonate Platform: A submarine or intertidal shelf whose elevation is maintained by active shallow water carbonate deposition. MORE

Calcium Carbonate

Science / Biology / Calcium Carbonate: Chemical that also occurs in limestone and marble. MORE

Bicarbonate Ions

Science / Biology / Bicarbonate Ions: A weak base present in saliva that helps to neutralize acids in food. MORE

Carbonate Ion

Science / Geology / Carbonate Ion: The anion group CO3 with a charge of minus two. MORE
