28 Lewis Acids and Bases The Lewis definition of acids and bases is more general than the BrØnsted- Lowry definition. A Lewis acid is an electron pair acceptor. A Lewis base is an electron pair donor. Lewis bases are structurally the same as BrØnsted-Lowry bases. Both have an available...
5.1 - Acids and Bases Many familiar compounds are acids or bases Classification as acid or base is based on chemical composition If you know a compound’s chemical formula, you may be able to identify it as an acid / base *Acids and bases can be very dangerous* They can be ...
