What is the pOH of an aqueous solution having a hydrogen-ion concentration of 6.83 × 10^-3 mol/L?

Question

Quizplus · Accepted Answer

The pOH of a solution can be calculated using the relationship between the hydrogen ion concentration ([H⁺]) and the hydroxide ion concentration ([OH⁻]) in water at 25°C, where the ion product of water (Kw) is 1.0 × 10⁻¹⁴. First, calculate the pH from the given [H⁺] = 6.83 × 10⁻³ M, then use the relationship pH + pOH = 14 to find the pOH.pH = -log[H⁺] = -log(6.83 × 10⁻³) ≈ 2.17pOH = 14 - pH = 14 - 2.17 = 11.83
