CaCO3 Properties|Calcium carbonate Museum|CALFINE

Calcium carbonate (CaCO 3) is composed of carbonate ion (CO 3 ion) and calcium ion (Ca ion). Usually calcium carbonate is a white rock (or powder), but if you enlarge CaCO 3 to the numerator level, you could see a figure like right picture. Besides you’d better know that mined limeston is not a calcium carbonate but contained a little impurities.
