Glacial Acetic/Sulfuric acid... lifespan?

[WarEaglemtn]

Do Glacial Acetic and Sulfuric acid go bad? Have located some in an industrial setting & in heavy plastic drums. It has been there for years. They are partly filled but with the pour stopper in tightly. No air but what was in them when open when last used years ago. Will the acid go bad just sitting like that when undiluted?

No. Those acids should be good for several centuries.

It shouldn't go bad in decades, even though some plastic (PVC specially) may go into solution.

That is an excellent finding
