Chemistry
pOH and pH Relation
Relate pH and pOH of aqueous solutions.
pH + pOH = 14 (at 25°C)
Formula Explanation
In pure water or dilute aqueous solutions at 25°C, the ion product of water is 10⁻¹⁴.
Variables Explained
pH = -log[H⁺]; pOH = -log[OH⁻].
Solved Example
If pH = 3, find pOH.
pOH = 14 - 3 = 11.
