Thats some serious stuff.
I know a long time ago 30+ years you could buy all sorts of things for the
amateur chemist.
Especially if you lived in a farm region.
Its funny how things have changed. Everything is so dangerous these days.
I will say I needed sulphuric acid for a large battery set and after a big
run around I did finally find a auto store that sold a gallon for $2.50.
Three X more then I needed but what the heck.
But my goodness what type of store are you talking about. Thats some serious
stuff depending on the concentration.
Regards
