Quizplus · Accepted Answer

The pH of a solution is calculated using the formula pH = -log[H+], where [H+] is the concentration of hydrogen ions in the solution. For a 8.1 x 10^-5 M HCl solution, the concentration of H+ ions is the same as the concentration of HCl because HCl is a strong acid and dissociates completely in water. Therefore, pH = -log(8.1 x 10^-5) = 4.09.
