Question

In what temperature water is Carbon Dioxide's acidity the highest? Chilled ocean water or room temperature ocean water?

Answer 1

Gases have a higher solubility in cold water. Colder temperatures will allow more `CO_2` to dissolve in water.

Explanation:

Gases like `CO_2` are more soluble in cold water, less soluble in warm water. Watch the video for a demonstration of this...

When carbon dioxide dissolves in water, it forms carbonic acid.

`CO_2 + H_2O -> H_2CO_3`

More carbon dioxide dissolved in water will produce more carbonic acid. More acid will produce a lower pH level of the water.

Hope this helps!
