A new technique of end-point indication in zero current bipotentiometric titration on two Pt electrodes is given. A cathode-ray oscillograph is used to replace the usual voltage-measuring instrument. The sudden jumping of a fluorescent spot on the fluorescent screen indicates the end-point of titration The method for indication of end-points is directly visual, sensitive, and much better than the conventional method.t
