Question

What is the pH of a solution with [H+] concentration of 1.86 x 10-5?

a.5.37 x 10-10
b.9.3
c.4.7
d.1.86 x 10-5

Answer 1

4.7

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(1.8 * {10}^( - 5) ) \\ = 4.7447`

We have the final answer as

4.7
