Sulphuric acid or Vitriol apparently played a major role in alchemy, so we're obliged to include it. The production was a bit different though, by heating types of iron sulfate and copper sulfate. But including a few more minerals is trivial.
Nitric acid, spirit of nitre or Aqua fortis (interesting link) is well within the tech limit. It's a component for Aqua Regia as well!
So those acids will be welcome and useful product of the alchemist's workshop. Nitroglycerin dates from 1847, so no. But who needs explosions if you can splash acid?
What about Aqua Vitae?
Also, I got an idea, like, you run into a large crowd of goblins, in full steel plate, and you ( and friends ) start throwing aqua regia, and fortis at them!
Aqua Fortis can't melt Gold and Platinum.
Aqua Regia can't melt tantalum, iridium, osmium, and titanium!
Aqua Vitae is the spirits [Alcohol] of wine [Alcohol] .
