Question

What is the pH of a solution if the pOH is 7.09?

Answer 1

pH = 6.91

Step-by-step explanation:

Recall that at 25 °C, we have the relationship:

`\displaystyle \text{pH} + \text{pOH} = 14.00`

Therefore, the pH of a solution with a pOH of 7.09 is:

`\displaystyle \begin{aligned} \text{pH} + (7.09) & = 14.00 \\ \\ \text{pH} & = 6.91 \end{aligned}`
