Question

What is the pH of this solution?
[H3O+] = 1 x 10-8 M

Answer 1

`\huge{ \boxed{8}}`

Step-by-step explanation:

pH is defined as the negative logarithm of the
`{H_3O}^(+)` concentration of a solution and it's given by the formula:

`\bold{pH = -log([{H_3O}^(+)])}`

From the question:

`[ {H_3O}^(+)] = 1 * 10^(-8) M`

`\therefore \: pH = - log(1.0 * {10}^( - 8) ) \\ = 8`
