What test can determine the difference between Na2SO4 and H2SO4?

For my AP chem class our final is a lab practical where you have to determine the the identity of 6 solutions. Ive gotten 4 of them and figured the last two are Na2SO4 and H2SO4. What test (ie. using indicators, other solutions) would help determine which is which? Thanks in advance
