Answer:
pH

OH- concentration 28.84
Explanation:
KOH dissociates into K+ and OH-. The ratio of K+ and OH- ion is 1:1
In any aqueous solution, the H3O+ and OH - must satisfy the following condition -
![[ H_3O^+] [OH^-] = k_w](https://tex.z-dn.net/?f=%5B%20H_3O%5E%2B%5D%20%5BOH%5E-%5D%20%3D%20k_w)
![[ H_3O^+] = \frac{k_w}{ [OH^-]}](https://tex.z-dn.net/?f=%5B%20H_3O%5E%2B%5D%20%3D%20%5Cfrac%7Bk_w%7D%7B%20%5BOH%5E-%5D%7D)

pH =
![- log [ H_3O^+]\\- log [2.857 * 10^{-13}]](https://tex.z-dn.net/?f=-%20log%20%5B%20H_3O%5E%2B%5D%5C%5C-%20log%20%5B2.857%20%2A%2010%5E%7B-13%7D%5D)
pH
![= - [-12.54]\\= 12.54](https://tex.z-dn.net/?f=%3D%20-%20%5B-12.54%5D%5C%5C%3D%2012.54)
