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.
Acids Bases and pH Scale. I. Acids *Acids are ionic compounds (a compound with a positive or negative charge) that break apart in water to form a hydrogen ion (H +). *The strength of an acid is based on the concentration of H + ions in the solution. The more H+ the stronger the acid.
Quick Answer. One of the main differences between acids and bases is that acids have a pH that is less than 7 and bases have a pH that is greater than 7. When dissolved in water, acids are substances that will cause the concentration of hydrogen ions (H+) to increase.
