Calcium Carbonate
Calcium Carbonate (CaCO3) is a ternary ionic compound (meaning more than two different elements) and composed of calcium (Ca) and the polyatomic ion carbonate (CO3). It naturally occurs in more than 4% of the Earth's crust in the form of chalk, limestone and marble. It is also used paper, plastics, paints, and coatings due to it's white color and brightness. In construction, it is used by itself as marble or limestone, but can also be made into mortar. It also is used in everyday life in the form of baking powder, toothpaste, dry-mix dessert mixes, dough, and wine.
Neat that chemicals found in limestone are also used in toothpaste.
ReplyDeleteThere are so many uses for this compound and I didn't even know it existed.
ReplyDeleteI'm on the same boat as Nathan Bertin, I've never heard of it but it seems really useful, especially in the toothpaste. That's important.
