The concentrations of acid and base used for titrations is important, as small additions must only change the pH level by small amounts for accuracy. Use Hess’s law to find an unknown enthalpy change, such as the reaction of anhydrous copper II sulfate with water to produce hydrated crystals. What is A Complexometric Titration – Introduction: Fill the burette with dilute acid. Volumetric titration calculations e. Titration is a procedure of careful addition of one solution to another solution a little at a time until a specificend point is reached. Mathematical calculation of the pH change as base is added to acid, shows that there is a large change in pH near the neutralisation point end-point of the titration.
