Problem

1. Three solutions have the following pH:
      pH = 4.3
      pH = 6.8
      pH = 11.5 

     a) Which solution contains the highest H3O+ ion concentration?
     b) Which solution is the most acidic?
     c) Which solution is the most basic?

2. What is the difference between a strong acid and a weak acid?


3. Calculate [H3O+] and [OH-] for the following three solutions
      a) pH = 9.5
      b) pH = 3.6
      c) pH = 7.0
