I'm a chemistry layperson looking for chemistry expertise regarding atmosphere composition.
Earth's atmosphere is oxidizing, but it was somewhat reducing in the distant past before photosynthetic life developed. Venus has an acidic atmosphere primarily composed of carbon dioxide which includes clouds of sulfuric acid. Some planetary bodies have reducing atmospheres containing hydrogen sulfide or carbon monoxide.
How do redox and acid-base reactions interact in the context of planetary atmosphere compositions? Specifically, what combinations of reducing/oxidizing and acidic/basic atmospheres are possible? Are there other planetary atmosphere types that should be considered when categorizing them?
Quick terminology question: Does it even make sense to refer to an atmosphere as acidic or basic?
