What happens to percent ionization of a weak acid as its concentration decreases?
A.It increases
B.It decreases
C.It stays constant
D.It becomes 100%
Explanation
Core Concept
Dilution shifts HA ⇌ H⁺ + A⁻ right (more particles side), so a larger fraction of the remaining acid ionizes — even though [H⁺] falls.
Correct Answer
AIt increases
