Overview. Bacterial pneumonia is an infection in one or both lungs. The bacteria cause the lungâs air sacs (alveoli) to become inflamed and engorged with pus, fluid, and cellular debris. This often impairs the bodyâs ability to exchange oxygen and carbon dioxide.he most common symptoms of bacterial pneumonia are: 1  cough with yellow, green, or blood-tinged mucus. 2  chest pain that worsens when coughing or breathing. 3  sudden onset of chills. 4  fever of 102 degrees or above (lower than 102 in older persons). 5  headache. 6  muscle pain. 7  breathlessness or rapid breathing. 8  lethargy.
In the Lewis model, a base is an electron pair donor. In water, by altering the autoionization equilibrium, bases yield solutions in which the hydrogen ion activity is lower than it is in pure water, i.e., the water has a pH higher than 7.0 at standard conditions.
The Lewis theory of acids and bases is more general than the one sided nature of the Bronsted-Lowry theory. Keep in mind that Bronsted-Lowry, which defines an acid as a proton donor and a base as a proton acceptor, REQUIRES the presence of a solvent, specifically a protic solvent, of which water is the usual example.he Lewis definitions of acid and base do not have the constraints that the Bronsted-Lowry theory does and, as we shall see, many more reactions were seen to be acid base in nature using the Lewis definition than when using the Bronsted-Lowry definitions.
