Principle
Potassium permanganate solutions which are used as oxidizing
measuring solutions in redox titrations can in most cases be
replaced by Ce(IV) solutions. These offer the advantages that they
do not change on storage and that the course of the redox titration
can be very conveniently followed by measuring the electrochemical
potential. The equivalent point can then be found by determination
of the inflection point of the potential curve which results from
plotting the measured values.
