What is pH?
pH is the measurement of the concentration of free hydrogen ions in a liquid. The pH of pure water is 7. Liquids with a larger concentration of hydrogen ions than water are acid and have a pH value less than 7. Liquids with a lower concentration of hydrogen ions on the other hand, are base and have a pH value higher than 7. The pH scale runs from 1 to 14.
