Club soda is a dilute carbonic acid solution
that usually also has a little salt in it.
Carbonic acid is a very weak acid which tends to decompose
into carbon dioxide and water,
in the presence of any other acid.

That is a good question,
because the ocean definitely needs some,
otherwise it has no carbon available for photosynthesis.

It was 21% in the 1980's.
I think it still is the same.
