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.
Or an acid-base reaction consists of the transfer of a proton from an acid to a base. KEEP THIS THOUGHT IN MIND!! Here is a more recent way to say the same thing: An acid is a substance from which a proton can be removed. A base is a substance that can remove a proton from an acid.
