Ellus
What is the pH of a 3.5 x 10-11 M
H+ solution?
pH = [?]

Answer 1

`pH=10.5`

Step-by-step explanation:

Hello,

In this case, since we define the pH as:

`pH=-log([H^+])`

We can directly compute it by using the given concentration of H⁺:

`pH=-log(3.5x10^(-11))\\\\pH=10.5`

For which we conclude it is a basic solution as the pH is greater than 7.

Best regards.
