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.
Cleaning products like bleach and ammonia are bases. Chemicals that are acidic or basic are an important part of chemistry. Several different theories explain what composes an acid and a base. The first scientific definition of an acid was proposed by the French chemist Antoine Lavoisier in the eighteenth century.
