Answer:
![[OH^-]=1.7x10^{-6}M](https://tex.z-dn.net/?f=%5BOH%5E-%5D%3D1.7x10%5E%7B-6%7DM)
Explanation:
Hello!
In this case, since the pOH of a solution can be computed when knowing the pH as shown below:

And therefore, the concentration of hydroxide ions based on the definition of pH:
![[OH^-]=10^{-pOH}](https://tex.z-dn.net/?f=%5BOH%5E-%5D%3D10%5E%7B-pOH%7D)
In such a way, we obtain:
![[OH^-]=10^{-5.78}=1.7x10^{-6}M](https://tex.z-dn.net/?f=%5BOH%5E-%5D%3D10%5E%7B-5.78%7D%3D1.7x10%5E%7B-6%7DM)
