Question 3

What is the pH of a solution with [H 30 +) = 1 x 10 -9 M?
1.0 x 10 -5
-9.0
5.0
-5.0
9.0

Answer 1

`\huge 9`

Step-by-step explanation:

The pH of a solution can be found by using the formula

`pH = - log [ { H_3O}^(+)]`

From the question we have

`pH = - log(1 * {10}^( - 9) )`

We have the final answer as

9
