Calculate the pH for an aqueous solution of pyridine that contains 4.15 × 10^-4 mol L^-1 hydroxide ion. A)2.41 × 10^-11 B)4.15 × 10^-4 C)3.382 D)10.618

Question

Quizplus · Accepted Answer

The pH of a solution can be calculated using the formula pH = 14 - pOH, where pOH is the negative logarithm of the hydroxide ion concentration. Given a hydroxide ion concentration of 4.15 × 10^-4 M, the pOH is -log(4.15 × 10^-4) = 3.382. Therefore, the pH = 14 - 3.382 = 10.618.
