Question

A solution has an [h ] = 3.92x10-5 m . what is the ph of this solution?

Answer 1

4.41

Step-by-step explanation:

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

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

where,

`[ {H}^(+)` is the hydrogen ion concentration of the solution

From the question,

`[ {H}^(+)` =
`3.92 * {10}^(-5) M`

`\therefore \: pH = - log(3.92 * {10}^( - 5) ) \\ = 4.41`
