Theory:
- Acid - electron-pair acceptor.In an equation, a Lewis acid gets more negative from the left side to the right.
Positive ions usually act as Lewis acids. - Base - electron-pair donor.In an equation, a Lewis base gets more positive from the left side to the right.
Negative ions usually act as Lewis bases. - Examples of Lewis acids and bases:
1. BrO3&minus + MnO2 → Br− + MnO4&minus- BrO3&minus is the Lewis acid
- MnO2 is the Lewis base
