AThe solubility product constant
BThe ion product constant of water
CThe acid-ionization constant
DThe rate constant of the forward step
Answer & Solution
Correct answer: C. The acid-ionization constant
1. Every equilibrium has its own constant, and acid ionization is an equilibrium.
2. Its constant is named the acid-ionization constant.
3. Comparing those constants ranks acids by strength on a single numerical scale.
4. The ion product of water is a different constant, describing water's own ionization.
