has pH 7, where [H⁺] = 1×10⁻⁷ mol/L Key points: pH less than 7: acidic pH greater than 7: basic (alkaline) pH exactly 7: neutral Similarly, pOH measures hydroxide ion concentration: pOH = -log[OH⁻] pH + pOH = 14 Application: Calculating pH from hydrogen ion concentration or vice versa is essential,
