pH = -log(H3O^+) and
(H3O^+)(OH^-) = Kw = 1E-14
will work all of these.
1. What is the pH of a solution whose [H3O+] is 1 X 10^ -5 M?
2. What is the [H3O+] concentration of a solution with a pH of 9?
3. What is the pH of a solution whose [H3O+] concentration is 3 X 10^-3 M?
4. What is the pH of a solution with a [H3O+] concentration of 1 X 10^ -12 M?
5.What is the [H3O+] concentration of a solution whose pH is 8.9?
