Dear All,
I am having 45 % H2SO4 acid which contains 2 % HNO3 and i want to remove only HNO3.
Please can you give me some idea.
Thanks & Best Regards,

Try heating the acid to boiling to concentrate the sulfuric acid. The sulfuric acid is not volatile but the nitric acid is so HNO3 gas will be
released. Be careful of splashing of the hot concentrated acid, and needless to say this must be done outside.
