Question

an unknown solution has a h3o concentration of 2.5 x 10-7 m. what is the ph of the solution and would it be classified as an acid or a base?

Answer 1

Step-by-step explanation:

pH is defined as the negative logarithm of the hydrogen ion or hydroxonium ion concentration of a solution. That is;

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

From the question

`[{H_3O}^(+)]` = 2.5 × 10-⁷ M

`pH = - log(2.5 * {10}^( - 7) ) \\ = 6.602`

From the results the solution can be classified as acidic since it's pH is below 7 that's the neutral region
