p H

is a measure of the concentration of hydrogen ions in a solution. The lower the

p H

, the higher the concentration of hydrogen ions, and the more acidic a solution is. Alkaline or basic solutions have lower concentrations of hydrogen ions and a

p H

7

. Which of the following substances has the highest

p H
