Acid-base titration

Acid-base titration is to determine as precisely as possible the concentration of the acidic solution or a basic solution using a pH measurement.

It is therefore necessary to measure the pH obtained at equivalence. Two methods are commonly used:

  • a graphical method suitable for measurements on graph paper: the method of tangents. 
  • a mathematical method implemented by using a computer: the method of derivation.

Position the parallel lines on the curve.
