The sulfuric acid atmosphere thing is interesting and that BBC video of science man corroding some peas is stupid. The reason we look for water on exoplanets as potential sources of life is because water is amphoteric, meaning it can act as an acid and a base, which makes it able to do loads of catalysis. That’s important because self-replicating chemical reactions (i.e. the foundations of anything we’d recognise as life) become more accessible because you can do acid catalysis and base catalysis all in the same environment.
Sulfuric acid is also an amphoteric molecule and can behave as an amphoteric solvent system, so actually it’s potentially very helpful for theoretically doing the same acid and base catalysis.
Dissolving up some peas in acid as a demonstration of how nasty sulfuric acid is to “life” is stupid, because our ~18% oxygen atmosphere absolutely fucking obliterates loads and loads of molecules - including phosphine actually, which spontaneously combusts on contact with air - and yet we’ve got life here. Dumb science reporting.
