Question

If the pH of a solution is 13.24 determine the concentration of OH- in this solution

Answer 1

`\huge{ \boxed{0.173 \: M}}`

Step-by-step explanation:

To find the concentration of
`{OH}^(-)` ions of the solution, we must first find the pOH of the solution by using the formula;

pH + pOH = 14

After the value of pOH is obtained we find the concentration of
`{OH}^(-)` ions by finding the negative antilog of the pOH obtained by using the formula;

`\bold{pOH = -log([{OH}^(-)])}`

From the question;

pH = 13.24

`\therefore 13.24 + pOH = 14 \\ pOH = 14 -13.24 \\ = 0.76`
