There was a past HSC question (1 mark) asking you what the name of H2S207 was. Would you be correct if you said any of the names for this compound, i.e. oleum or pyrosulfuric acid or the others I'm aware of? Is more one correct than the other?

tommykins · 22 Sep 2008, 12:54 AM

oleum would suffice.

JMill · 22 Sep 2008, 9:09 AM

Yes, Oleum is sufficient for a single mark and is preferred for the HSC

Oleum. *Increases reliability*

Why is oleum preferred though, over 'pyrosulfuric acid'?

brenton1987 · 26 Sep 2008, 12:11 PM

I would have said its disulfuric acid.

Technically oleum is a group of compounds with the formula xSO₃^.H₂O or H₂SO₄^.ySO₃

ask teachers who are hsc markers. i would have written oleum.
