What is the pH of a 0.046 M HClO₄(aq)at 25 °C? (K_w = 1.01 × 10^-14)

Question

Quizplus · Accepted Answer

HClO is a strong acid, so it will dissociate completely in water to form H+ and ClO-. Therefore, the concentration of H+ in the solution will be equal to the concentration of HClO, which is 0.046 M. The pH of the solution can be calculated using the formula pH = -log[H+], which gives a pH of 1.34. Note that the value of the acid dissociation constant (K_w) for HClO is not needed to answer this question, as its status as a strong acid allows us to assume complete dissociation.
