Question

PH & POH

What is the pH of Barq's Root Beer with a (H+] of 9.25 x 10-5 M?
a) 4.0
b) -4.0
c) 10.0 d) 0.000095

Answer 1

4.0

Step-by-step explanation:

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

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

From the question we have

`ph = - log(9.25 * {10}^( - 5) ) \\ = 4.03385`

We have the final answer as

4.0

Hope this helps you
