Ocean Acidification

How does gaseous carbon dioxide affect the pH of the ocean?
In this investigation, we will model the effects of atmospheric carbon dioxide on the pH of water.

How does gaseous carbon dioxide affect the pH of the ocean?

Water covers about 75% of the Earth’s surface, with most of the water in the oceans. The pH of the water on Earth’s surface affects living and non-living systems. The pH of water is primarily determined by two factors: the concentration of carbonate ions from weathering, and the absorption of carbon dioxide from the atmosphere.

In this investigation, we will model the effects of atmospheric carbon dioxide on the pH of water.
