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.
