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.
An acid is a substance that donates hydrogen ions. Because of this, when an acid is dissolved in water, the balance between hydrogen ions and hydroxide ions is shifted. Now there are more hydrogen ions than hydroxide ions in the solution. This kind of solution is acidic. A base is a substance that accepts hydrogen ions.
