Question

A solution has a hydronium-ion concentration of 0.0029 M.What is its pOH?
A)2.54
B)16.54
C)8.16
D)​5.84
E)11.46

Quizplus · Accepted Answer

To find the pOH, first calculate the pH using the formula pH = -log[H3O+]. With [H3O+] = 0.0029 M, pH = -log(0.0029) ≈ 2.54. Then, use the relation pH + pOH = 14 to find pOH = 14 - 2.54 = 11.46.
