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...
17、uffer pH changes until the renal excretion of acids and bases comes into play.Abnormalities in respiratory function reduce the efficiency of this buffering system(such as emphysema or a smokers lung),and drive the body toward a constant state of respiratory acidosis.Cigarettes smoke also has ...
