2. What are the hydrogen ion concentrations for solutions with the following pH values? (a) pH = 4.0 (b) pH = 11.0 (c) pH= 8.0
3. What are the hydroxide ion concentrations for solutions with the following pH values? (a) pH = 6.0 (b) pH = 9.0 (c) pH= 12.0
4. Give the pH of eaach of the following solutions: (a) [H+] = 1 x 10(to the -4) (b) [H+] = 1 x 10(to the -9) (c) [H+] = 1 x 10(to the -12) (d) [H+] = 0.001
5. Write the formula and the name for two monoprotic, two diprotic, and two triprotic acids.
