Answer:
6.91
Explanation:
To find the pH we must first find the pOH
The pOH can be found by using the formula
pOH = - log [ {OH}^{-} ]
We have
[tex]pOH = - log(8.2 \times {10}^{ - 8} ) \\ = 7.086186...[/tex]
pOH = 7.09
Next we use the equation
pH = 14 - pOH
We have
pH = 14 - 7.09
We have the final answer as
6.91
Hope this helps you
