AIt is present at a low concentration
BIt has a very small molar mass
CIt only works at high temperature
DIt does not ionize fully in water
Answer & Solution
Correct answer: D. It does not ionize fully in water
1. Weak is a statement about ionization, not about how much acid is in the bottle.
2. A weak acid does not ionize fully in aqueous solution.
3. A concentrated solution of a weak acid is perfectly possible.
4. Confusing weak with dilute is the classic error this definition guards against.
