Question

What is the PH of a solution that has an H = 1.5 x 10-4 M

Answer 1

`\huge{ \boxed{3.8}}`

Step-by-step explanation:

pH is defined as the negative logarithm of the hydrogen ion
`[{H}^(+)]` or hydroxonium ion(
`{H_3O}^(+)`) concentration of a solution. That is

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

From the question

`[{H}^(+)]` = 1.5 × 10-⁴ M

`pH = - log(1.5 * {10}^( - 4) ) \\ = 3.823 \approx3.8`

We have the final answer as

3.8
