Titration of a weak - strong base:
While internal generation cell is used along with platinum auxiliary electrode the latter must be placed within a separate compartment as display in Figure of Unit 5. For the titration of acids, a silver anode might be used along with a platinum cathode in the presence of KBr as the supporting electrolyte. A silver electrode should also be placed in a separate compartment. It might be placed within a tube closed along with a sintered discs at its lower and could be inserted straight into the test solution.
A bromide concentration should be 0.05 M. Endpoint could be detected along with the user of indicators. Potentiometric endpoint might also be probable on the availability of the instrument tube a pH meter along with a glass electrode.
Titration of a weak / strong base in the hydrogen ions is produced at a platinum anode.
