Quizplus · Accepted Answer

The relationship between pOH and pH in aqueous solutions at 25°C is given by the equation pH + pOH = 14. Given a pOH of 4.33, the pH is 14 - 4.33 = 9.67. The hydronium ion concentration, [H3O+], can be found using the formula [H3O+] = 10^-pH, which gives [H3O+] = 10^-9.67 = 2.1 × 10^-10 M.
