Activity 9: Ocean acidification
Ocean acidification is a fatal consequence of climate change for many marine species. But why does CO2 make the oceans acidic and what are the direct consequences for the marine ecosystem?

- If the slightly acidic solution produced is to be further used for activity 10 "Release of CO2 by the oceans", the solution should be as weakly acidic as possible and only a few "bubbles" of CO2 should be introduced. If the solution is too acidic, the release by heating will not succeed to the extent that a clear turnover can be seen with the indicator.
