Could a reported rainfall pH of 3.1 actually be realistic?

A quick literature search seems to confirm Gordons estimation, even at the scale of a whole bucket: [T]he annual mean pH, based upon samples collected weekly during 1970-1971 and weighted ...

Could a reported rainfall pH of 3.1 actually be realistic?

Raindrops gain a small amount of acidity as they fall through carbon dioxide in the air, but that's not what this question is about. Raindrops commonly start off as ice crystals which have to nucleate ...

Will increased level of ocean acidity lead to more frequent acid rain?

More likely, it works the other way: increased acid-forming compounds in the atmosphere are the cause of more ocean acidification. Pio et al. [1] report measurements of sulfur and nitrogen compounds ...

Will increased level of ocean acidity lead to more frequent acid rain?

Essentially no. Acid rain was especially a problem when coal and other industries let up vast amount of sulphur which made strong sulphuric acid rain which could kill trees. Volcanoes can also have ...

Signatures of acid rain at KT boundary

Estimated sulfur release 325 gigatonnes = 325,000 teragrams. The numbers in this diagram are in teragrams Sulfur Cycle so the release is $\approx 1000\times $ today's annual sulfur cycle. I think ...

What would the pH of rainwater be if carbon dioxide in the atmosphere doubled?

"Cutting the $CO_2$ in half would yield about 5.9." (A valid approach because we expect reversibility in chemistry and physics.) [pH of 5.9 for 200 ppm $CO_2$] Atmospheric $CO_2$ of 200 would be ...
