Rabies is a very serious viral infection that targets the brain and nervous system. You can catch rabies if you are bitten by an infected animal and haven't been vaccinated. It's almost always fatal once symptoms develop, but can be prevented if treatment is given promptly after exposure.
**The pH scale is a measure of the hydrogen ion concentration. It spans from 0 to 14 with the middle point (pH 7) being neutral (neither acidic or basic). Any pH number greater than 7 is considered a base and any pH number less than 7 is considered an acid. 0 is the strongest acid and 14 is the strongest base.
Here is a list of ten common bases with chemical structures, chemical formulas and alternate names. Note that strong and weak means the amount the base will dissociate in water into component ions. Strong bases will completely dissociate in water into their component ions. Weak bases only partially dissociate in water. Lewis bases are bases that can donate an electron pair to a Lewis acid.
