11. True or False, in a basic solution, there are "no" (not even a very small Molarity) of hydronium ions ([H1+])?
12. How does the pH value and the concentration (in M) of hydronium ([H1+]) ion relate to each other.
13. If you go down 1.0 pH unit, how does the amount of concentration (in M) of hydronium ([H1+]) ion change?
14. There is a 1.0M H2SO4 solution, 1.0M HCl solution and a 1.0HF solution. It was found that the relative pHs of the solution went from lowest, middle, to highest, respectively. Explain why the pH range was true for the three solutions.
