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.
A hydrogen and a hydroxide ion can also join together to form a water molecule. In pure water, hydrogen and hydroxide ions are present in a 1:1 ratio since the only source of these ions is the ionization of water. Acids and bases are substances which change the balance of hydrogen and hydroxide ions in water. In this lesson, we will first explore the chemistry of acids and bases, then we will show how to calculate their concentration mathematically.
