How Does Calcium Carbonate React With Vinegar?

Calcium carbonate produces a weak chemical reaction with vinegar, which is an acetic acid, by releasing carbon dioxide. A simple experiment that demonstrates the reaction is to soak an egg, which has a calcium carbonate shell, in vinegar, which completely dissolves the shell in a matter of days.

Lesson 9 Softening

If allowed to enter the distribution system in this state, the high pH would cause corrosion of pipes and the excess calcium carbonate would precipitate out, causing scale. So the water must be recarbonated, which is the process of stabilizing the water by lowering the pH and precipitating out excess lime and calcium carbonate.

Covering Ocean Acidification Chemistry and Considerations

Jun 24, 2008 · Less carbonate makes it more difficult for corals, mollusks, echinoderms, calcareous algae and other shelled organisms to form calcium carbonate (CaCO 3), their major mineral building block.Also, when carbonate concentrations fall too low, already formed CaCO 3 starts to dissolve. So, marine organisms have a harder time making new shells and maintaining the ones they've already got.

Explaining Climate Change

Pteropods and corals both construct their shells with calcium carbonate. As carbon dioxide increases in the atmosphere above the ocean, some is absorbed by the ocean and causes a decrease in pH. This process, known as ocean acidification, makes calcium carbonate less available to be used as a building material.
