• The plot that we know of as a graph was the brainchild of the French mathematician-philosopher Rene Descartes (1596-1650) A titration curve is a graphical representation of the pH of a solution during a titration.
  • In both cases, the equivalence point is reached when the moles of acid and base are equal and the pH is 7.
  • This also corresponds to the color change of the indicator.
  • In a weak acid-strong base titration, the.
  • pH is greater than 7 at the equivalent point.
  • In the case of a strong acid-weak base titrate, the pH.
  • is less than 7.
