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.
Weak bases exist in chemical equilibrium much in the same way as weak acids do, with a base dissociation constant (Kb) indicating the strength of the base. For example, when ammonia is put in water, the following equilibrium is set up: Bases that have a large K b will ionize more completely and are thus stronger bases.n chemistry, a weak base is a chemical base that does not ionize fully in an aqueous solution. As BroenstedâBrÃ¸nsted lowry bases are proton, acceptors a weak base may also be defined as a chemical base in which protonation is. Incomplete this results in a relatively pH ph compared to strong. bases
