The following problems will help you prepare for your quiz next time on this topic. Check
the key and get stamped when finished. This page goes on pg. 104 in your notebook.
Formulas:
pH = - log [H+]
pOH = - log [OH-]
14 = pH + pOH
[H+] = 10^-pH
[OH-] = 10^-pOH
Problems:
1. Determine the pH and pOH of each of the following solutions and indicate whether each
is acidic, basic, or neutral.
Solution
a) Milk, [H+] = 3.2 x 10-7 M
b) Pickle Juice, [H+] = 2.0 x 10-4 M
c) Beer, [H+] = 3.2 x 10-5 M
d) Blood, [H+] = 4.0 x 10-8 M
e) Seawater, [H+] = 3.0 x 10-9 M
