"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 ...

Scientists have discovered a spongy form of calcium carbonate (CaCO3), a material found in limestone, chalk, ... Blue mussel shells after initial treatment with acetic acid.

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), ...
