What is Ocean Acidifiion?
Many marine organisms that produce calcium carbonate shells or skeletons are negatively impacted by increasing CO 2 levels and decreasing pH in seawater. For example, increasing ocean acidifiion has been shown to significantly reduce the ability of reef-building corals to produce their skeletons.
What happens when acid reacts with limestone? | …
Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don''t dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions
