Answer:

-.30

Explanation:

H2SO4/sulfuric acid/dihydrogen sulfate is a strong acid, meaning that it easily releases an H+. You have to be careful with this problem, however, as H2SO4 is really only a strong acid for one of its hydrogens. In other words, after it becomes HSO4- upon releasing an H+, it is no longer a strong acid and therefore should not be factored into our calculation.

Now, moving onto the calculation, there are two key things we need to carry it out. First is the pH equation. pH = -log [H+]. And second is the concentration of H2SO4, which is equivalent to the concentration of that H+ released: 2.0 M.  Simply plug in your values.

pH = -log [2.0].

pH = -.30
