Found all over the world, calcite is the most stable form of calcium carbonate and is the main mineral found in limestone.

This image from Augustana University researcher Caleb DeWitt displays a colorized scanning electron micrograph of calcium carbonate crystals—specifically, the polymorph known as vaterite.

In this reaction we will investigate the reaction between ethanoic acid and calcium carbonate. All acids produce carbon dioxide gas when reacted with a metal carbonate.

So, if we have calcium carbonate and we heat it, it breaks down to produce calcium oxide and carbon dioxide. Gethin: OK, I know you're poised with your pen and your flip chart. But, before that ...
