Answer: ![[OH^-] =10^{-10.75}=1.778\times 10^{-11}M](https://tex.z-dn.net/?f=%5BOH%5E-%5D%20%3D10%5E%7B-10.75%7D%3D1.778%5Ctimes%2010%5E%7B-11%7DM)
Explanation: pOH is defined as negative logarithm of hydroxide ions. More is the number of ![[OH^-]](https://tex.z-dn.net/?f=%5BOH%5E-%5D)
ions , lesser is the pOH and vice versa.
pH + pOH = 14
![10.75=-log[OH^-]](https://tex.z-dn.net/?f=10.75%3D-log%5BOH%5E-%5D)
![[OH^-] =10^{(-10.75)}=1.778\times 10^{-11}M](https://tex.z-dn.net/?f=%5BOH%5E-%5D%20%3D10%5E%7B%28-10.75%29%7D%3D1.778%5Ctimes%2010%5E%7B-11%7DM)
