10. Nitric acid and nitrous acid are both acids that you would not want to spill on your feet.But one is much more acidic than the other and would do real damage. Draw themolecular structures of each of these and explain - based on what you learned in thismodule - why nitric acid (pKa =-1.35) is much more acidic than nitrous acid (pKa = 3.15).
