# The pH of a solution is 7.0. What is the pOH?

Jun 12, 2017

$\text{pOH} = 7.0$

#### Explanation:

A fundamental equation to know regarding $\text{pH}$ is that (near ${25}^{\text{o""C}}$),

$\text{pH" + "pOH} = 14.00$

That is, near ${25}^{\text{o""C}}$, the sum of the $\text{pH}$ and $\text{pOH}$ is always $14.00$.

Therefore,

"pOH"= 14.00 - "pH" = 14.00 - 7.0 = color(red)(7.0

Since the $\text{pH}$ and $\text{pOH}$ are equal, this solution is said to be neutral; i.e. it is neither acidic nor alkaline (basic).
