Question 5 (4 points) Definitely don't get this in your eyes! H2SO4 is a strong acid while H, PO, is a weak acid. Which of the following reasons correctly explains why that's true? There are between 1 and 4 correct answers. la H2SO, is a stronger acid than H3PO4 because H,SOhas fewer protons to lose. H2SO, is a stronger acid than H, PO, because the conjugate base, HSOA. is less stable than the conjugate base, H PO H,SOis a stronger...
