As a gas, carbon dioxide does not have a pH.

However, it is slightly soluble in water and when it dissolves in water, the resultant solution is slightly acidic. Slightly acidic solutions have a pH less than 7 which is considered "low".

The pH for carbon dioxide?

pH applies only to aqueous systems. Dissolved in water, carbon dioxide is very mildly acidic.


Will the presence of algae affect the pH of water?

I think so because carbon dioxide lowers the pH levels and algae absorbs carbon dioxide. So when the algae takes in the carbon dioxide, the pH levels should rise. -will


If a person is not exhaling carbon dioxide which then becomes carbonic acid in the blood is this raising the pH or lowering the pH?

Yes, the presence of carbon dioxide in the blood lowers pH so therefore when it is removed the pH increases. However the act of removing carbon dioxide itself does not affect pH, rather it results because of less carbon dioxide.

What is pH value for carbon dioxide?

Gases do not have a pH as pH is a measure of hydrogen ion concentration in solution in water. Carbon dioxide is sparingly soluble in water and mostly forms very weakly ionised carbonic acid. pH will be close to 7.
