I've checked multiple sources: macquarie, wikipedia and even notes in class. Can't seem to get a grasp on it. Like you said, its a weak acid... Any ideas?

it's exactly the second ionisation of sulfuric acid. It's a weak acid but it is quite a strong weak acid (if that makes sense). It does not completely ionise but quite a lot of it actually does. And remember that 1 change in pH is equivalent to 10 fold change in [H+]. Thus pH of 1.9 for 1M means that it's about 10 times weaker than HCl.
