Question

Calculate the pH of a solution with [H3O+] = 2.3 x 10-12 M.

O 11.63
O 3.20
O 12.00
O-12.36

Answer 1

`\huge{ \boxed{11.63}}`

Step-by-step explanation:

pH is defined as the negative logarithm of the hydrogen ion or hydronium ion concentration of a substance.

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

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

From the question;

`[ {H_3O}^(+)]` = 2.3 × 10-¹² M

`\therefore pH = -log(2.3 * {10}^(-12)) \\ = 11.63`
