Question

If hydrochloric acid has a [H+] of 1.2 x 10-2 M, what is the pH?

1.9
0 1
1.2
O
8

Answer 1

1.9

Step-by-step explanation:

Answer 2

1.9

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(1.2 * {10}^( - 2) ) \\ = 1.920818...`

We have the final answer as

1.9
