  • The pH scale is maintained to range from 0-14 or maybe 1-14, but neither is correct.
  • The pH range does not have an upper nor lower bound.
  • The pH is an indication of concentration of H+.
  • For example, at a pH of zero the hydronium ion concentration is one molar, while at pH 14 the hydroxide ion concentration is one molar.
  • Typically, the concentrations of H+ in water in most solutions fall between a range of 1 M (pH=0) and 10-14 M (pH=14).
  • Hence a range of 0 to 14 provides sensible (but not absolute) “bookends” for the scale.
