Answer: pH = 5.78 POH = 8.22

Explanation for pH: The pH can be found using the formula pH = -log[H+]. To find [H+], we can use the fact that Kw = [H+][OH-] = 1.0 x 10^-14 at 25°C. Solving for [H+] gives [H+] = 1.67 x 10^-6 M. Plugging this value into the pH formula gives a pH of 5.78.

Explanation for POH: The pOH can be found using the formula pOH = -log[OH-]. Plugging in the value of [OH-] gives a pOH of 8.22.
