Weak Acid + Strong Base Salt

$$K_h = \frac{K_w}{K_a} \qquad h = \sqrt{\frac{K_h}{C}} \qquad \text{pH} = 7 + 0.5 \cdot (\text{p}K_a + \log_{10}C)$$

Concept: Calculates the hydrolysis properties and basic pH behavior of a salt formed from a weak acid and a strong base.

Notation:

• $$K_h$$ = Hydrolysis constant;
• $$h$$ = Degree of hydrolysis;
• $$C$$ = Salt concentration;
• $$K_w$$ = Ionic product of water;
• $$K_a$$ = Acid dissociation constant.
