Question
According to Arrhenius theory, bases are substances (or species) that generate hydroxyl ions OH- (aq). Identify the base which doesn’t follow the Arrhenius concept.
- NaOH
- NH3
- MgO
- KOH
The correct answer is: NH3
Ammonia is a base, but it does not contain hydroxyl ions. Arrhenius concept does not give any explanation for it.
