Answer to Question #163847 in General Chemistry for Dan Warner

Question

 Compute for the concentration of perchloric acid solution if the pOH = 5.52

Answer 1

pH = 14 - pOH = 14 - 5.52 = 8.48

There is a mistake in the task: pH of the strong acid can't be more than 7

So, if there should be pH = 5.52 in the task, the the solution:

pH = -lg(H⁺)

[H⁺] = 10^-pH = 10^-5.52 = 3.02 × 10^-6

HClO₄ is a strong acid, which means C_HClO4 = [H⁺] = 3.02 × 10^-6 (M)

Answer: C_HClO4 = 3.02 × 10^-6 M.
