Weak Base pOH

$$\text{pOH} = 0.5 \cdot (\text{p}K_b - \log_{10}C)$$

Concept: Provides a direct calculation for the pOH of a weak base solution using its dissociation constant and concentration.

Notation:

• $$\text{p}K_b$$ = Negative logarithm of base dissociation constant ($$-\log_{10}K_b$$);
• $$C$$ = Molar concentration.
