Question #598b1

Answer 1

`pH=4.7`

Explanation:

The concentration of `OH^-` in the solution is:

`[OH^(-)]=5.6xx10^(-10)M`, which will help us determine the `pOH` of the solution, which is later on will allow us to find its `pH`.

`pOH=-log[OH^(-)]=-log(5.6xx10^(-10))=9.3`

Therefore, the `pH` of this solution could be found by:

`pH=14-pOH=14-9.3=4.7`
