9. The pH of a solution is calculated by using the formula pH = -log[H*], where [#*] is the concentration of the hydronium ions. a) If the pH of a solution is 4.2, what is the concentration of the hydronium ions? b) A strong acid has a pH less than 3. If the concentration of the hydronium ions is 1.6×10 in a particular solution, is the solution a strong acid? Explain.
