Question

What is the PH of a solution with a concentration of 5.2 x 10-8 M H3O?

Answer 1

Answer:

7.28

Explanation:

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

$pH = - log [ { H_3O}^{+}]$

From the question we have

$ph = - log(5.2 \times {10}^{ - 8} ) \\ = 7.28399$

We have the final answer as

7.28
