Carbonate-acid reaction. Limestone reacting with the acid contained in white vinegar. This is an example of an acid-carbonate reaction. Limestone consists of calcium carbonate, and the acid here is ethanoic acid (also called acetic acid). The reaction produces a metal salt (here, calcium acetate), carbon dioxide (the bubbles seen here) and water. This reaction is equivalent to that which occurs when acidic rain (due to dissolved carbon dioxide producing carbonic acid) reacts with and erodes limestone.
