pH and pOH Relationship

$$\text{pH} + \text{pOH} = \text{p}K_w = 14 \text{ (at 298 K)}$$

Concept: Establishes that the sum of pH and pOH values is constant for any aqueous solution at a specific temperature.

Notation:

• $$\text{p}K_w$$ = Negative logarithm of the ionic product of water ($$-\log_{10}K_w = 14$$).
