In our case, the calcium carbonate and acetic acid combine to form three new products: Water, a salt called calcium acetate (which is immediately dissolved in the water so we don't see it), and ...

The egg shell in vinegar experiment demonstrates how calcium carbonate reacts with acetic acid. About 95 percent of an eggshell is made up of calcium carbonate.

"The calcium carbonate in a pearl reacts with the acetic acid in vinegar to produce calcium acetate, water and carbon dioxide," Jones wrote in the current issue of the Classical World journal ...

The researchers concluded that the material was formed from extra calcium carbonate that didn't react completely with the acetic acid.

Vinegar is an acid called acetic acid. When it combines with calcium carbonate in eggshell and in the antacid tablet, a chemical reaction takes place. In the reaction, the atoms in the acetic acid and ...

When the two mix, the carbonate takes up the hydrogen ions from the acetic acid and becomes carbonic acid, which breaks down into carbon dioxide and water.

Glossy paint can be difficult to remove, especially if you're working with a textured ceiling. This vinegar trick could help ...

Chiral structures are formed in numerous processes including biomineralization of calcium carbonate. Here, the authors demonstrate that the chiral, hierarchically-organized architecture of the ...

Calcium carbonate (CaCO3) is a natural product found in many settings, including the minerals aragonite1 and calcite2; the sedimentary rocks limestone3 and chalk4; and animal structures such as ...
