Question

What is the pH of a solution with an H3O+ concentration of 5.67 x 10-4 M?

a. 1.00
b. 3.25
C. -1.00
d. -3.25

Answer 1

3.25

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(5.67 * {10}^( - 4) ) \\ = 3.2464`

We have the final answer as

3.25

Hope this helps you
