1
Q

A
- Arrhenius
- Brosted-Lowry
- Lewis theory
2
Q
Explain Arrhenius theory
A
Acid: sub dissociates to give H+ ions when dissolved in water
Base: sub dissociate to give OH- when dissolved in water
3
Q
2 limitations of Arrhenius theory
A
Cannot account for:
- Acid-base rn occurring in other solvents
- Acid-base rn in gaseous state
4
Q
Explain Bronsted-Lowry theory
A
Acid: H+ donor
Base: H+ acceptor
5
Q

A
Acid=e- pair acceptor
Base= e- pair donor
