SO2 does not easily become SO3. That requires high temperature combustion with oxygen. SO2 can react with H2O to become H2SO3, sulfurous acid, but a big study established that there were no "acid rains." Just an acidic buildup in groundwater soaking in conifer needles.
The way I remember it acid rain was the environmentalist's rallying cry of the 1980s. In the 90s they moved onto the Ozone Hole scare. I'd have to do some historical research to locate the exact transition time.
I think you’re right. I was born in 83 so I remember both but might have then mixed up. I remember an avid rain reference in Bill Murray’s “Christmas Carol” comedic remake “Scrooged” with people literally screaming as their faces burned from acid rain landing on them 😂
Dont forget sulphur dioxide S02 will then oxidise to suphuric acid H2SO4... so the added problem of acid rains.

What is this, 1992? Who says “acid rain” anymore? 😆
Ok but seriously, maybe slightly more acidic PH but the term “acid rain” was SUCH a 90s liberal fearmongering term.
“Captain…..PLANET!!!”
