Answer

$[OH^-] \approx 1.98 \times 10^{-13}$; It's a acid solution.

Work Step by Step

1. Knowing that [H+] * [OH-] = $10^{-14}$, find [OH-]. $[OH^-] \times [H^+] = 10^{-14}$ $0.0505 \times [OH^-] = 10^{-14}$ $[ OH^-] = \frac{10^{-14}}{0.0505}$ $[OH^-] \approx 1.98 \times 10^{-13} $ 2. Calculate the pH of the solution. $pH = -log[H^+]$ $pH = -log(0.0505)$ $pH \approx 1.2967 $ 3. Because pH < 7, the solution is considered acid.
