HClO4 perchloric acid is a strong acid, which means it completely dissociates in water. The dissociation equation is:HClO4 H+ + ClO4-Since the concentration of HClO4 is 0.1M, the concentration of H+ ions will also be 0.1M. To find the pH of the solution, we can use the pH formula:pH = -log10[H+]pH = -log10 0.1 pH = 1The expected pH of a 0.1M solution of HClO4 is 1.
