sulfuric acid

I want to purify my 50% sulfuric acid. I want to reduce the water. What should i do, simply boil it to 90-100 degrees Celsius ?

Linke the title im looking for a small quantity of sulfuric acid :)

If i have Base and want to Salt out: - What i have to do? - Use Acetone/Methanol and desired acid, ok. On all acids: The Base have to be dry! -> MgSO4 as a drying agent. But i was thinking that the use of phosphoric acid is different to sulfuric and of course: no HOW TO is available here...

Probably Nitrogen Dioxide, but it quacks like Bromine. Why the sudden reaction on addition of Hbr? Could anyone shed a light on this? Thanks!

Hi there, i saw many synthesis methods here and they all seem a bit complicated to me. My situation is: i got 1l of the yellow oil (i guess its BMK?) and the person, who gave it to me, didn't have a proper instruction for me. I just got the info, that i need to put the oil in a big dish made out...
