text: More accurately, a single formula that describes the titration of a weak acid with a strong base from start to finish is given below:
  where
  " φ = fraction of completion of the titration (φ < 1 is before the equivalence point, φ = 1 is the equivalence point, and φ > 1 is after the equivalence point)
  :  = the concentrations of the acid and base respectively
  :  = the volumes of the acid and base respectively
