Question

What is the poH of a
6.5 x 10-12 M OH solution?
pOH = [?]

Answer 1

11.2

Step-by-step explanation:

Answer 2

`pOH=11.2`

Step-by-step explanation:

Hello,

In this case, by knowing that the pOH is defined in terms of the concentration of OH⁻ as shown below:

`pOH=-log([OH^-])`

We directly compute with the given concentration:

`pOH=-log(6.5x10^(-12))\\\\pOH=11.2`

Moreover, fur such pOH, the pH will be:

`pH=14-11.2=2.8`

Which means that such solution is an acid solution.

Best regards.
